Background: my system is a windows 11 on 24H2 that debloated with a tool called TALON by raven software

#

One of the things people do when debloating Windows is removing Microsoft Edge. That browser can feel like a pest you can’t control, so some users choose to remove it manually—sometimes even through registry edits.

But here’s the catch: Removing Edge can also remove Microsoft Edge WebView2 from the registry, and many applications—including Modrinth—depend on WebView2 to function properly.

#

Step 1: Check if WebView2 is Missing

open powershell and run:
Get-AppxPackage -Name Microsoft.WebView2Runtime

if nothing happens, then webview is missing.
Example output:
PS C:\WINDOWS\system32> Get-AppxPackage -Name Microsoft.WebView2Runtime
PS C:\WINDOWS\system32>

#

Example Output if Webview is installed:

#

Step 2: Reinstall Microsoft Edge WebView2

If WebView2 is missing, you’ll need to reinstall it manually:

You can download the WebView2 Evergreen Runtime from Microsoft: https://developer.microsoft.com/en-us/microsoft-edge/webview2/

If you don't know your system type, you can check your system type by going to Settings > System > About and looking under 'System type'.

Make sure to download the x64 version unless you’re on a 32-bit system (which is rare for Windows 11 users).

Run the installer as administrator and follow the instructions.

#

Note: My system is a windows 11 machine on 24H2. I personally made the mistake of installing the x86 webview Evergreen Standalone Installer, it SHOULD have been x64 instead.

#

Now, verify the installation by running the following command in PowerShell:
Get-AppxPackage -Name Microsoft.WebView2Runtime

if it outputs correctly, then you can stop here.

#

Once installed Restart your machine, check if Modrinth launches.

If the output is missing or Modrinth still won’t launch, proceed to Step 3

#

Step 3: Checking Registry Editor

How do you know that EdgeWebView isn't missing?
To know that C:\Program Files (x86)\Microsoft\EdgeWebView\ isn't missing, navigate to it on file explorer

Do win + r and enter regedit

now navigate to this path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EdgeUpdate\Clients

system wide path:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients

user specific path:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\EdgeUpdate\Clients

look for a key named:
{F2C5EFC8-4FE3-4B37-BED9-7D2E1B470290}

#

If the key exists, check if the information is similar to this:

#

If this key or path itself is missing, WebView2 is not properly registered, then you can proceed to Step 4.

Note: Edge and EdgeUpdateDev are NOT the same as EdgeUpdate

#

Step 4: Manually adding a Regedit Entry

Open notepad and paste this:

#

Then you save the file name as WebView2Fix.reg
IMPORTANT NOTE: save it as ALL FILES and not as a .txt file

Double click to the file.
Click "Yes" when asked if you want to add the changes to the registry.

Note: You don’t need to worry about where you save the .reg file. Once you run it, Windows copies the changes into the Registry, so the file itself is no longer needed. You can delete it afterward if you want.

#

Step 5: Restart and Final Check

open powershell and run:
Get-AppxPackage -Name Microsoft.WebView2Runtime

If it outputs correctly and modrinth launches, it is completely fixed!
