Thanks - I'll investigate this.
Note, that Cabal adding an additional 7 levels of directory (and ~70 characters) to the path for executables can exacerbate this.

I reported several odd and inconsistent results that I can't understand, and after some further trials, a few more data points, but still confused.
A directory of files, cabal build runs fine, then trying to execute; I get three different results;
Linking D:\CS\Courses\long path\All Solutions\dist-newstyle\build\x86_64-windows\ghc-8.10.1\apl-0.0.1\build\apl\apl.exe ... Seems fine.
Then; from that same shell (PS) in the same directory - From cabal run: Fails PS D:\CS\Courses\long path\All Solutions> cabal run Up to date D:\CS\Courses\long path\All Solutions\dist-newstyle\build\x86_64-windows\ghc-8.10.1\apl-0.0.1\buil d\apl\apl: createProcess: invalid argument (Invalid argument)
From using the explicit path: Fails PS D:\CS\Courses\long path\All Solutions> dist-newstyle\build\x86_64-windows\ghc-8.10.1\apl-0.0.1\build\apl\apl.exe Program 'apl.exe' failed to run: The application has failed to start because its side-by-side configuration is incorrect.

From going to the dist folder: runs fine. PS D:\CS\Courses\long path\All Solutions> cd dist-newstyle\build\x86_64-windows\ghc-8.10.1\apl-0.0.1\build\apl PS D:\CS\Courses\long path\All Solutions\dist-newstyle\build\x86_64-windows\ghc-8.10.1\apl-0.0.1\build\apl> apl.exe "APL: Examples and labs"
I get a few other errors & results sometimes; copy the full directory to somewhere else, "cabal clean", And it won't build, "no target specified", even though the entire folder is identical.
Again; every time just copying the entire directory, no editing of any files, just running cabal as above. Any hints or ideas why I am getting these issues & errors?
GHC 8.10.2 Cabal 3.2.0.0 (Windows 10) ---------------------------------------------------------------------- -- PS: One more... I (again) copied the entire directory to another place and retested, in that case "cabal run" did run, but gave results from a different file in the directory (multiple tests there, only one run from Main.hs, same .cabal file), and can run it by explicit path or "cabal run".
All results should be "DSem_imp", one is from a different file, "DSem_impc" ?? Certainly looks like they should all be running the same apl.exe. ??
