If you had problem with 2.6.3, does the following work for you ?
http://fixounet.free.fr/2.6/xp2.exe
You just made the "compatibility mode" for standard?
It works like the first version but still not starts in WinXP SP3 without...
AND:
No start after crash.
It just starts and quit instantly - until the crash.py file is deleted manually.
yes, for Xp & 2003 the compatibility flag is set by the installer
I'm not so sure if it works for you or not ?
Confirmed for the crash.py preventing it from starting
Yes, it works perfectly for me. Setting the compatibility manually in the first 2.6.3. installer version also worked for me.
I have found the root issue, a new version should out soon
