‘An attempt was made to load a program with an incorrect format’ when installing Visual Studio 2022 extension

-- -- 706

Hi

Every time I try to install a Visual Studio 2022 extension I get error below at the end. These extensions are all legitimate official releases from established suppliers.

Here is error log for Microsoft Installers for VS 2022 extension;

19/08/2022 23:21:17 - Microsoft VSIX Installer

How can I fix this and get the extensions installed?

Thanks

Does the vendor of the extension say their extension works with VS2022?
VS2022 is the first 64-bit version, and the fact that you get System.BadImageFormatException leads me to suspect the extension may not be 64-bit compatible.

Do you have any extensions that have installed OK?
For example, Live Share 2022, Visual Studio Spell Checker (VS2002 and Later)?

If others are installed OK, I can only suggest that you check with the vendor.

I assume you've not got an ARM machine and are running VS2022 ARM?

HI David

Live Share 2022 was already installed from way back. Trying to update it to latest version gives the same error with below log. Its a regular Intel based PC.

Thanks

I'm out of suggestions then.
Tried a repair installation of VS?
Perhaps Fuslogvw (or Fusion++) might show some details of what's amiss?

Hi @-- -- , please also try to update VS 2022 to the latest version. Besides, did you change some settings on your machine/OS?
