Having reinstall XP Home, but the message is still popup,
any other ideas?

Can you contact Support? They'll send you a special program to find out what is missing.

Our version of GS is 7.50 (It's been a while since I've had a chance to use GS). I've just been asked to create something using GS, so I came here to make sure I've got the latest version.

I didn't see anything in the update guide about upgrading across multiple versions- Could you tell me if it's okay to go directly from 7.50 to 7.77, or should I download and install each intermediate version?

Thanks

it wont be a problem updates are full install, not version to version.

Same goes for me.
When I run the Compiler from WED I got the Message posted above, when I run it from the Gamestudio-Folder, it says this:

I'm just got a email from the Support Team
that said they'll upload a new 7.77 version
next week and it will solve my problem.

Thank you very much jcl and the Support Team.

The reason of the wwmp2wmb starting problem is still not 100% clear.

If you encounter such a problem, please download a different wwmp2wmb version here:

Please let us know if this version works for you - or not. In the latter case, please give some info about the OS version, service pack version, and language version of your PC.

I'll be away next week, but think that we can upload the final, official 7.77 version in June after my return.

As I got no more problem reports with 7.77, the latest version, 7.77.4, is now available on the download page.
