Cannot load Keeper Plugin for Edge

Question

When trying to load the Keeper plugin for Microsoft Edge we keep getting the error "An error has occurred, download interrupted." Here are some things we have tried:

• Reset browser
• Tried installing under one of our admin accounts
• Disabled Netskope service
• Installed Chrome, was able to install the plugin in Chrome
• Confirmed the computer was in the correct OU in AD

The only thing I have yet to try is to see if I can download the plugin while logged in using a local admin account. Any ideas of what may be causing this? I welcome your feedback, this is a weird one!

Hello Alderson, Jon,

Here are some steps you can use to troubleshoot this

1. Microsoft Edge Extension Store Reachability

Even if Chrome works, Edge uses a different store (Microsoft Edge Add-ons). Check if access to the following domain is blocked, redirected, or intercepted:

https://microsoftedge.microsoft.com/addons

Try this:

• Visit the URL above directly in Edge. Can you browse the store without any redirection errors?
• Open Developer Tools (F12) → go to the Network tab → then try installing the plugin again and watch for failed requests or status codes (403, 407, etc.)

2. Group Policy / Endpoint Security Blocking Extension Install

Check if a Group Policy or endpoint security rule is:

• Preventing Edge extension installs
• Restricting it to specific domains or IDs

Press Windows + R, type in gpedit.msc and enter

Navigate to Computer Configuration > Administrative Templates > Microsoft Edge > Extensions
Check for any policy that might block you from download the plugin

Also check in registry editor

Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\ExtensionInstallBlocklist

or HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Edge

3. Try Local Admin with No Network Policies Applied

You mentioned you haven't tried using a local admin account. This is highly recommended to test next.

Log in with a local admin

Disconnect from the domain (if possible)

Try installing the extension in Edge

This can help determine if a domain policy, security suite, or inherited restriction is at play

4. Edge Profile or Cache Issues

Even though you reset the browser, there may be Edge profile-level issues or corrupted cache affecting the extension download.

Try:

Creating a brand new Edge profile (Settings → Profiles → Add profile)

Then attempt the install from that new profile
Hope this help with your issue.

Hello, Alderson, Jon

Thank you for your feedback. I understand that you are having trouble installing the extension. Here are some troubleshooting solutions:

This is the most likely cause, especially in an AD environment. There may be specific GPOs for the Edge browser rather than Chrome that restrict the installation or download of extensions.

1. On the affected computer, open the Edge browser, enter edge://policy/ in the address bar, and press Enter. This will display all active policies applied to Edge. Carefully check for any policies related to extension installation, download paths, security settings, or proxies.

Run the gpresult /r command to view group policies applied to users and computers.

Run the gpresult /h C:\report.html command to generate a detailed HTML report, then open it. In the report, look for policies related to “Microsoft Edge,” particularly the following categories:

Computer Configuration\Administrative Templates\Microsoft Edge\Extensions

Computer Configuration\Administrative Templates\Microsoft Edge\Downloads

User Configuration\Administrative Templates\Microsoft Edge\Extensions

User Configuration\Administrative Templates\Microsoft Edge\Downloads

Look for policies such as “Block installation of extensions,” “Allow specific extensions,” “Configure download directory,” and “Scan download files for malware.”

Damaged Edge browser internal settings or profile

Even though you reset the browser, sometimes the reset may not be thorough enough, or specific profiles may still have issues.

Try a new Edge profile: In Edge, go to edge://settings/profiles, try adding a brand-new profile (without logging into any Microsoft account), then switch to that profile and see if you can install the Keeper plugin. This can rule out damage to the current user profile.

 

2. You plan to try logging in and installing using a local administrator account. If successful: This strongly indicates the issue is related to domain user profiles, Group Policy Objects (GPOs) applied to domain users, or domain user permissions. You can further investigate permission differences between domain users and local administrators, or confirm which GPOs are applied exclusively to domain users.

If it fails: This means the issue is more widespread and may be related to the computer's configuration itself (system-level GPOs, system-level security software, the Edge installation itself), rather than just the user profile or domain user permissions.

I look forward to your feedback.

Good morning, just wanted to run by what I have done.

• Opened the Edge browser /policy page, found no policies set
• Checked for for the mentioned registry keys, I did not find any Edge keys in the paths mentioned
• Tried a new profile, same issue
• Opened up the developer tools, tried to download the plugin, all status numbers were listed as 200
• I am able to download and install the plugin from two of the 4 locations that the customer runs from
• Tried an OU that had inheritance blocked, same issue.
• Starting to run out of options here, wondering if perhaps it is related to an update that is somehow blocking this plugin from installing. Any further thoughts are appreciated!
