I recently installed VS 2019 Community on my D: drive. When I try to install an extension, I get dialog saying that the installation failed and referencing a log, which contains the following:

Hi cjohnson1440,
Welcome to MSDN forum.
Did you install Extension from Visual Studio -> Extensions -> Manage Extensions?
After checking the log file you shared I suggest you could try below steps to troubleshoot.
#1. Repair Visual Studio from Visual Studio Installer -> find VS 2019 -> More -> Repair.
#2. Try to install in safemode. (open developer Command Prompt for VS 2019 -> type devenv /safemode to start VS in safe mode)
#3. Try to reset settings. (open developer Command Prompt for VS 2019 -> type devenv /resetsettings)
#4. Try to manually uninstall and re-install this extension. (Extensions -> Manage Extensions)
If this issue persists, I need your help to collect the setup log and for further research. Please download and run this collect.exe tool, go to %temp% folder and find the vslog.zip file, upload it to https://onedrive.live.com/ and share the link here.
Hope all above could help you and any feedback will be expected.
Best Regards,
Tianyu
