Hey golux, you are awesome!!
I was going through your post and at first I thought you made a typo when you said you ran 'cpanp i PAR::Packer'
I thought you just accidently added a 'p' to cpan but a quick google introduced me to cpan plus.
Figuring they may have a better version I uninstalled PAR::Packer using ppm.
I attempted to run 'ppm install MinGW' but it said it was already installed (no missing packages). I then copied and pasted your 'cpanp' command.
I didn't see any errors.
Next, I ran the same pp command I had been running and gui1.exe was created without error which is what I had been seeing all along.
I ran the .exe and for the first time it worked! A little slow the first time like you said.
And to think I was just about ready to drop this issue for a while. Thanks again!
