I will now try to reinstall the last version of Xampp that worked as it supposed to for me : 1.7.4 VC 6
Update: now Vista is warning me that UAC is deactivated on my system, this should be ok i think, or is better to reactivate it????
I had another error telling me that i must run Xampp from the C directory, but i followed the instruction i found here and now seems to be better, as described.
"Just remove Key “Install_Dir” completely from Windows Registry [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\xampp] and Xampp Control will start without error message. Xampp Control then shows “No installer package found” in status window after start."
