Cannot load extension on VS 2019

[fotico]

Installed VS 2019 v16.11.3 with C++ Clang tools for windows v12 I then installed clang-powertools v7.6.0 and clangformat v12 from the extension dialog.

After installing the extensions and restarting visual studio, a dialog box informs me that "The RunClangPowerToolsPackage package did not load correctly". All the icons of the toolbar are greyed out. The ActivityLog.xml shows the following entry:

<type>Error</type>
    <source>VisualStudio</source>
    <description>SetSite failed for package [RunClangPowerToolsPackage]Source: &apos;mscorlib&apos; Description: An error occurred while sending the request.&#x000D;&#x000A;</description>

I tried uninstalling the extension, deleting everything in %AppData%/ClangPowerTools (which was already empty), then reinstalling it - same thing happens.

Hi @fotico,

The problem is from Visual Studio, not from the extension.

But this may resolve your problem:

• Delete this folder: C:\Users[username]\appdata\local\microsoft\VisualStudio\16.0\ComponentModelCache

• An alternative from StackOverflow: https://stackoverflow.com/questions/31741405/error-setsite-failed-for-package-apachecordovatoolspackage

Hello, I am facing the same Problem with VS 2017 Express. I also deleted the extension and reinstalled, and deleted the ComponentModelCache directory, but the error still is there.

Hi @SevHub,

Do you still have the same problem?

Kind regards, Marina

I'll be closing this issue due to insufficient information.
