converting a6 demo to full prog with key.exe

Hello, I didn't know where to ask this. But I bought a new Vista windows computer and want to run my purchased a6 standard on Vista. The demo of a6 installed fine. Even the tencical demo with the water room etc plays fine. When I tried to open my key.exe file into the gamestudio folder, the unzip program told me some errors, like "can't create ... some filenames. I paid for the full version of a6, love it and have been running it for years. Has anyone else installed a6 on thier Vista computer and can tell me how to run key.exe on it? Thanks.

this is an issue that should be handled by conitec. whenever you have key issues, they should resolve it for you. they might have to confirm your ownership of the license first. ask JCL.

that's most likely a vista issue... you can try running it as admin. i don't use vista so i don't know how specifically but try searching.
