Dang mate. What a screw-around.
I am so sorry this shit has happened to you.
I am also running Win 7 (64 bit) and I'm not having any issues since changing the installer program.
Glad to hear that you have it running now.
I hope that you find it useful and efficient.
Don't forget there is an updated compile console on the download page too.
No installation required, just extract it to the same directory.
Happy mapping.
