net sdk 6.0.6 hostfxr.dll is not found

[roofiq]

Hello,

I have upgraded application from net 5 to net 6 and this error started to appear when executing it:

Failed to load the dll from [C:\hostedtoolcache\windows\dotnet\host\fxr\6.0.6\hostfxr.dll], HRESULT: 0x800700C1
The library hostfxr.dll was found, but loading it from C:\hostedtoolcache\windows\dotnet\host\fxr\6.0.6\hostfxr.dll failed
  - Installing .NET prerequisites might help resolve this problem.

Here is a detailed COREHOST_TRACE:

I was trying to run it on hosted agents and on self hosted (VM) - same.
I am using latest net sdk version 6.0.301, in this topic #27787 it was said, that it will resolve the issue but seems like nothing has changed.

Any ideas how to approach it?
Thanks

Hello, just sharing with a resolution I have found.
I have reviewed COREHOST_TRACE when running it locally and it was using x86 runtimes, so I have registered self hosted agent with x86 architecture, specified demands and it successfully run :)
