Visual Studio 2019 (Community Edition) - Cannot install/update Extensions

-1

It's a fresh installation of Visual Studio 2019 Community Edition on my fresh installation of Windows 10 (64 bit) on Intel i3 laptop.

Whenever I attempt to install an extension (for example, CodeMaid), I get COM ClassID not found error. I'm not sure why is this error. From google search and after referring to some articles, I think this error is due to 32bit COM on 64bit machine. Visual Studio attempts to look for the COM CLASSID under 64bit registry, but it fails since it might be under 32bit registry. This is just a wild guess.

Just to add to it, "Report a Problem" under "Help" is also not working for me, but NuGet Package Manager is working well; I could download and reference NuGet packages. Not sure if this is anywhere related to the Extensions, but just keeping this information posted for you.

Please help me to resolve this error.

I'm copying the complete error log of error I got when I attempted to install CodeMaid extension. This is surely not a extension-specific error because I get the same error when I attempt to Update extensions like "Live Share".

Take a look at following error log for details:

Actually, when you uninstall VS, you could do a deep clean about VS on your PC and then reinstall it.

When you uninstall it, please enter C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe to run the program. And it will uninstall all VS2017 and VS2019 version with the whole data.

If uninstalling VS2019 did not work, you can try this.

Besides,

delete folders like 16.0_xxxx under C:\Users\xxx(current user)\AppData\Local\Microsoft\VisualStudio`.

When you finish it, make sure that there is no folder of your current VS2019 version(community*professional**enterprise*) under C:\Program Files (x86)\Microsoft Visual Studio\2019.

====================================

Then, right-click on the vs_installer-->click run as administrator and then install the related extension development workload like this:

Last, when you finish the installation, please test it again.
