Hi !
Don't know where to put this thread because I did not find a main topic for the computer itself.
I recently installed Win 7 pro x64 in another partition of my computer . I previously used XP X64 as you may see in my profile.
When I want to merge the "computers" , same machine , same name , it says that they are not compatible .
This is the same physical machine, same IP etc..
So why ? I don't want to crunch anymore on xp but on 7.
Thanks for your time

Time overlap; you were using both at one stage (27th Feb for W7 and XP right up to 1st Mar), so the server identifies them as being different systems and thinks they could not be the same as they were both in use at the same time. It's not a GPUGrid issue, it affects all Boinc projects.
