Let‘s get started conquering this pesky (but easily beaten!) error.

Why Discord? A Quick Backstory

First, a quick primer in case you‘re new to Discord:

Launched in 2015, Discord allows gamers to easily chat via text, voice and video. It offers a fast, free alternative to legacy apps like TeamSpeak and Skype.

But Discord rapidly expanded beyond its gaming roots. Today, over 150 million people use it each month to build close-knit communities around shared hobbies, interests and experiences.

From knitting to stock trading discussions…developer networking to dance class groups. You name it, there‘s a passionate Discord server for it!

What makes Discord so addictive?

For starters, it‘s 100% free while offering premium-grade voice/video quality. You can access Discord conveniently via desktop or mobile apps rather than clunky browsers.

And intuitive chat channels, moderation tools plus robust bots let users create vibrant online spaces where vibrant communities take shape organically.

No wonder Discord has seen a 95% increase in daily voice chat minutes amid 2020‘s stay-at-home orders. It keeps people feeling connected, included and entertained even under lockdown. That special social glue is irreplaceable for many right now.

But enough background…

Let‘s dig into conquering the infamous Discord install failure issue once and for all!

Discord Install Fails: Symptoms and Underlying Causes

If you‘re reading this section, I‘ll bet you just tried installing Discord, only to be greeted by an unpleasant ‘Installation Has Failed‘ error glaring back.

We‘ll cover fixes shortly. But first, let‘s break down root causes and symptoms so you know what you‘re dealing with.

When Discord‘s installer fails, what exactly goes wrong?

Well, you successfully download the setup files from Discord‘s website without issues.

But when launching the main installer program (DiscordSetup.exe), it abruptly quits halfway through.

No matter how many times you retry running it, the same cryptic ‘Installation Failed‘ error keeps popping up. Argh! 🤬

Why does this happen?

Likely because another program or system setting blocks Discord from properly unpacking its files.

Without access permissions, or due to software conflicts, installation processes prematurely fail. Leaving you without your essential Discord access!

The most common underlying issues causing frustration here include:

  • Missing admin rights: Discord requires full read/write permissions to integrate properly. Regular user accounts often lack adequate access.

  • Antivirus conflicts: Overprotective antivirus apps may falsely detect Discord as an ‘intruder‘, blocking vital install procedures involuntarily as a result.

  • OS version incompatibilities: Discord‘s install process relies on specific Windows features which sometimes don‘t translate cleanly from legacy OS editions. Leading to abrupt failures despite the setup file itself opening without issues.

  • Driver issues: Like Windows conflicts above, faulty Drivers can severely disrupt expected behavior of system processes that Discord setup relies upon. Again resulting in a failed install.

  • Corrupted Discord/system data: When old Discord files or components of your Windows OS get severely damaged, it knocks vital background processes out of whack…taking your Discord install down with it!

As you can see, installation failures happen somewhat easily if certain stars misalign.

Luckily each root cause above is fixable, as you‘ll learn in the next section!

7 Field-Tested Ways to Resolve Discord Install Failure

If you feel like pulling your hair out over Discord yelling "Failed to install, please try again…" each time – I totally get it! 😠

Fortunately, as a cybersecurity professional, over the years I‘ve compiled a mental toolkit with proven methods to get Discord properly up and running in these frustrating scenarios.

Let‘s run through them one-by-one:

#1. Launch as Administrator

Often, simply relaunching Discord‘s installer with heightened admin permissions does the trick. This overrides restrictive settings temporarily.

To launch as admin:

  1. Browse to your newly-downloaded DiscordSetup.exe file.

  2. Right-click and select Run as administrator.

  3. Click ‘Yes‘ on any permission confirmation popup thereafter.

Running as admin allows Discord to install itself smoothly without nagging roadblocks. It takes just seconds!

If launching the installer directly as admin still fails, try opening Command Prompt as admin first, then running Discord‘s installer from there. This doubles down on admin permissions granted to finalze the install.

#2. Obliterate Old Discord File Remnants

An incomplete prior Discord uninstall – or corrupted leftover files – can certainly cause fresh installs to fail.

Clearing out old remnants fixes this.

To purge previous Discord data:

  1. Open File Explorer and delete the %AppData%\Discord folder. This covers application data.

  2. Also wipe %LocalAppData%\Discord to eliminate locally stored info.

  3. For good measure, check %Temp% and delete any Discord-related files situated there as well.

With your system‘s slate wiped clean of old Discord data,launching the Discord installer once more often resolvesInstallation Failed errors.

#3. Fully Uninstall Prior Versions

Did you already have Discord installed previously?

If so, fully removing the older installation is wise. Discord‘s installer quarrels with itself when detecting past versions already present.

You can quickly uninstall apps via Windows 10‘s Start menu. But for a more thorough removal, use the Control Panel instead:

  1. Open Control Panel > Uninstall a Program
  2. Locate Discord and select Uninstall.

This scrubs registry entries and file leftovers more cleanly before your reattempt.

And don‘t forget to restart your PC afterwards – clearing out memory!

#4. Use Windows Compatibility Mode

If your Windows version is rather outdated or you‘re on an aging machine, embracing compatibility mode often saves the day:

To reinstall Discord in compatibility mode:

  1. Right-click DiscordSetup.exe then select Properties.
  2. Go to the Compatibility tab.
  3. Check the Run Compatibility Troubleshooter box.
  4. Follow the steps shown thereafter to set up and apply optimal compatibility settings tailored to your system.

What does compatibility mode do exactly?

It essentially tricks Discord‘s installer into thinking it‘s running on an earlier Windows release. This curbs reliance on newer native features that may be missing or glitchy within outdated systems.

By imitating a past Windows edition this way, Discord sidesteps bumps causing abrupt installation failures earlier. Pretty ingenious!

This trick especially helps rescue aging Windows 7 machines that otherwise struggle playing nice with newfangled software.

#5. Forcibly End Background Discord Processes

If previous failed installation attempts left Discord processes and tasks lingering, this can sometimes obstruct fresh installers.

So we‘ll manually force-quit them:

  1. Hit CTRL+Shift+Esc to open Task Manager.
  2. Click More details if prompted.
  3. Select the Details tab.
  4. Scan the list and look for any entry named Discord.
  5. Right-click each Discord item found and select End task.

This forces background processes and threads related to Discord to close instantly. Clearing the path for our fresh installer!

#6. Add Exceptions and Temporarily Disable Antivirus

Overzealous antivirus and firewall tools are notorious for meddling – often detecting legitimate apps as false threats unexpectedly.

If your protection software quarantines vital Discord installation files or blocks procedures entirely, this quickly causes heartbreaking failure.

Here‘s how to correctly add exceptions and bypass overbearing antivirus blocks:

  1. First, explicitly add Discord‘s installer (DiscordSetup.exe) as a trusted exception within your antivirus console. This prevents auto-quarantines down the road.
  2. Still seeing issues? Open Task Manager then the Startup tab. Locate your security app and click Disable to force-close it. Don‘t leave protection disabled permanently though!

With stubborn antivirus knocked out temporarily, Discord should begin installing smoothly at last. 👍

Once setup completes be sure to re-enable your antivirus via Task Manager again. Safety first!

Pro Tip: Top-tier antivirus apps like BitDefender offer "Gamer Mode" – tailor-made to avoid obstructing popular games/chat tools. Turn this on as added protection if present!

#7. Try Discord‘s Testing/Experimental Builds

If exhausting other troubleshooting steps still ends in sorrow, installing one of Discord‘s beta test versions sometimes saves listeners.

On their website, you‘ll find:

  • Discord PTB (Public Test Build) – Previews upcoming features/improvements. Updated weekly.

  • Discord Canary – Bleeding-edge nightly preview edition for hardcore early adopters.

I must offer caution here: beta and nightly channels naturally come with more bugs and less polish.

But desperate times call for desperate measures! If you still struggle getting Discord‘s main branch functioning, bite the bullet and attempt installing a rough-around-the-edges early access edition instead.

Cross your fingers it behaves better and at least gets you chatting until more stable updates come down the pipeline. 🤞

Once installed, you can directly transfer over data and settings from Canary/PTB builds into the main Discord desktop app later with ease.

Avoid Repeat Installation Nightmares: Words of Wisdom

With any luck, at least one resolution method covered above finally gets Discord properly installed and back in working order for you! Give yourself a celebratory snack. 😋

However no one wants to endure nasty ‘Failed to Install‘ surprises ever again down the road if avoidable.

As a cybersecurity advisor, here are my top 3 proactive tips to prevent repeat Discord install failures and tech headaches in general:

Regularly Update Your Windows Version

Discord‘s programmers optimize their installer for the latest Windows builds and features. Each OS revision tries playing nicer with newly-developed software.

So by keeping your Windows version regularly updated via Settings > Windows Update, you equip your computer to handle apps like Discord flawlessly with each passing month.

It‘s a simple way to avoid being left behind!

Know Safe Uninstall Procedures

As covered earlier, incomplete uninstalls leaving file/registry remnants often hamper future installs.

The safest approach is always using your Operating System‘s purpose-built uninstall tool rather than blindly deleting entries manually. This minimizes leftover clutter.

For Windows 10, Settings > Apps > Apps & Features lets you cleanly remove programs without residue. Quick, painless, and thorough!

Back Up Your System Periodically

However disciplined your maintenance practices, computers inevitably develop hiccups. Files get corrupted; Updates cause glitches; Crashes lose data… you‘ve likely endured this rollercoaster before! 🎢

So make matters infinitely easier on yourself by scheduling periodic system backups. This lets you roll back your operating system to an earlier ‘known good‘ state when modern issues emerge.

Reverting to a previous restore point often circumvents recently-developed problems without losing precious data or configs.

Free tools like Macrium Reflect make regular imaging dead simple. Give your future self the gift of reliability!

Let those tips sink in, and may your future Discord adventures install smoothly from here on out. 😎
