My uproject files no longer have associations after having installed the binary 4.4.3 engine from the launcher (previous version was 4.2.1). Hence, I cannot switch versions on my projects, nor generate VS files.
I have tried associating .uproject with C:\Program Files\Unreal Engine\Launcher\Engine\Binaries\Win64\UnrealVersionSelector.exe, but this does not work (“Invalid command line”)
