Probably not. I assume that it uses the registry settings. Modelsim
looks that it has its root at unix (TCL for scripting etc).

not exist, even on CURRENT USER and LOCAL_MACHINE

>  "SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\emacs.exe"
>  "SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\runemacs.exe"

also not found, I'm using win7 x64!

I will check it again
