operable program or batch file.

Note "set in the error message. Something clearly goes wrong there.

I don't have a windows haskell development setup at the moment. It'd be great if someone that does could look into this! Want to try figuring out what's going wrong @arrowd?

I had a look at this, and was able to reproduce the error message with just with the process library. It is probably related to this long standing issue: haskell/process#51.

Closing as an upstream issue. If someone wants to work on getting this fixed in process, I'd be happy to work with them on it (I maintain the library)
