Hi Eliot,

I think I made that mistake.

I installed to C:\cygwin but I updated to C:\Desktop.

To prevent any issues, I'll just reinstall from scratch.

Another reason is that extracting the file.tar.xz files results in some 
administrator right issues.

So, I'll just make sure it's a clean install, no merge errors or missing 
files.
