Version Switch Issues

Development Programming & Scripting C++

When I right click > Switch Unreal Engine Version 5.4 in the Explorer on a uproject file. I get an Error “Failed to generate project files”.

Precompiled rules assembly ‘C:\Program Files\Epic Games\UE_5.4\Engine\Intermediate\Build\BuildRules\UE5Rules.dll’ does not exist.

When switching to 5.3 it says:
ERROR: UnrealBuildTool.dll not found in “…..\Engine\Binaries\DotNET\UnrealBuildTool\UnrealBuildTool.dll”

Might be that I have deleted the Intermediate content? I was able to create the sln files before but I had different issues later on and tried different things. Is it right that Intermediate folders can always be deleted?
Please advise

Try verifying engine installation

Thank you very much, this helped. I am at the point where I was yesterday now and when Building a solution the Error Code:

MSB3073 The command ““C:\Program Files\Epic Games\UE_5.4\Engine\Build\BatchFiles\Build.bat” OVRLipSyncDemoEditor Win64 Development -Project=“C:\Projects\UnrealEngine\OVRLipSyncUnrealDemo_03\OVRLipSyncDemo.uproject” -WaitMutex -FromMsBuild -architecture=x64” exited with code 6.

Do you know by any chance how to make this work?
Best regards and thank you for your time
