Unexpected Chrome problems in Horizon

[ProjectD22]

Hi there!

A few weeks ago I got into a strange problem with one of our vdi images. Google Chrome completely stopped rendering sites. Every site is white even the settings won't work anymore. There are no errors displayed on the site. The only thing I see ist the error favicon in the tab.

Here's what I tried:

• Starting Chrome with --disable-gpu
• Reinstalling Chrome
• Updating Chrome to the newest version.
• Deleting my AppVolumes Disk

I've already asked the chrome community but they couldn't help me either. So I'm trying it here.

Here's some more infromations you might need:

- We are using VMware Horizon 7.3.2

- Running on vCenter 6.0.0

- The OS used is Windows 10 Enterprise 1607

- Chrome Version  73.0.3683.86 (Enterprise edition)

- We are using VMware App Volumes 2.14.0.184 (Chrome is not installed on a App Volumes Disk. It's installed on the Windows Image)

If you need any more informations, feel free to ask.

Thank you in advance!

We experienced something very similar.  For us it seemed to be something with symantec end point and either an update from them or a windows update on top of SEP.

The fix we found was

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\svdriver\Parameters

edit HookInjectionWhitelist and remove the chrome.exe line

Thank you very much for your answer!

We are indeed using SEP on our vdi machines. Unfortunately there are no keys or dwords in that directory of the registry. So there is nothing to remove from there.

But you might be right that SEP is the one causing the problems. I'm going to do some more research on that.

Thank you!

As an aside, try to rename chrome.exe to chrome1.exe or something else and see if it works.  I realize it probably won't be an actual fix long term, but might give you a chance to limp by, and would probably verify it's the same issue

I might shouldn't have done that. The chrome installation now stopped working entirely. I've changed chrome.exe to chrome1.exe. When I try to start the .exe file I'm getting an application error. I need to redeploy this machine again.

Anyway, you were right! I just removed SEP from my VDI image and chrome is working perfectly fine now. I'm gonna do a reinstall to see if anything changes.

Thanks again!

Also I just realized in picture above you went to wrong key.

You went to HKLM/system/currentcontrolset/system/....

You need to go to HKLM/SYSTEM/CurrentControlSet/Services/svdriver/Parameters

Not the Services not System

Well that's emberrassing. It works now. Thanks you so much for you help!
