Protel 99 SE on Windows 7 / Vista

As i am a programmer in most of my working time i come across problems and i try to find solutions for this problems.

Recently someone sent me a Protel 99 SE DDB file and ask me to review the schematics. I installed Protel 99 SE and i could not open the SCH document.

I have searched using Google to find some some solutions and came to discover that there is something about compatilibility with Windows 7 / Vista etc.

I had disabled UAC “User Access control”, checked directory and files rights, started the app as administrator, disable the “hide file extensions for known file types” in windows files settings. Nothing seemed to work.

Then i realized something:

1. My windows 7 boot partition was on drive D:

2. I have installed Protel 99 SE as defaulted to C:

I quickly uninstalled everything and installed it again on Windows  partition… ( D: in my case ) … and voila !

I was able to edit SCH documents once again !  It took me few long hours to discover the problem and i hope i might help someone else by posting it!
