Which part won’t work? I have things mostly working with my folder structure mentioned in the original post. I just haven’t worked with it for very long to know if I’m missing something I’ll regret later. I’d hate to have to move around 25GB of files because I’m off by one folder.
I certainly hope the location of the engine install isn’t as rigid as you say and it must be in the folder the launcher is installed at. That doesn’t make for a very good source control setup.
I had found UnrealVersionSelector-Win64-Shipping.exe, but it didn’t seem to help much. I lost the context menu entries for “switching engines” when I uninstalled the downloaded version of the 4.4 engine. Now it won’t come back, even after running UnrealVersionSelector-Win64-Shipping.exe. I had to manually set the .uproject file to be opened by my engine as mentioned in #2.
