Failed to load the dll from [C:\Users\***\AppData\Local\AzureFunctionsTools\Releases\4.10.1\cli_x64\hostpolicy.dll], HRESULT: 0x800700C1
An error occurred while loading required library hostpolicy.dll from [C:\Users\***\AppData\Local\AzureFunctionsTools\Releases\4.10.1\cli_x64\]
C:\Program Files (x86)\dotnet\dotnet.exe (process 1748) exited with code -2147450750.
x86 version of dotnet is used as shown in the log while the library to load is 64:
C:\Program Files (x86)\dotnet\dotnet.exe
To fix this issue, we need to ensure 64 bit dotnet is used.
At the moment, x86 dotnet path is before the x64 version:
Move this x64 version above the x86 version as the following screenshot shows:
Click OK button to save the changes.
Restart Visual Studio 2022 or other IDEs/CLIs you are using to make the variable effective.
You can verify this by starting a new PowerShell window:
