Upgraded to BOINC 7.0.25 on to 2 PCs.
Both PCs graphics cards fail to process where previously they were perfectly happy to crunch prior to the upgrade to BOINC 7.0.25.
Similar error messages ... GPU does not exist blah, blah for every previously-perfectly-OK-GPU-enabled project.
Reverted to 6.12.34.
XP Pro (AGP card, Gallatin) reclaimed all settings ... sublimely.
W7 64-bit (OpenCL card, 2600K) failed miserably and needed much manual intervention just to get back to a clean slate which then required project re-attachment etc etc

Discuss.

FWIW - my advice is to ignore upgrading to 7.0.25 until an adult gets involved.
FWIW2 - I am not subscribed to this thread and I do not read PM's so trolling is a waste of effort.

The difference between 0 and 1 is greater than the difference between 1 and 1,000,000,000

I wonder if the developers could have given slightly more prominence to the change in Service Mode behaviour under Windows XP?

v6.12.34: GPUs can be used
v7.0.25: GPUs can't be used

Just guessing that this is the issue here.....

From the Release Notes:

Known Issues on Windows

Protected Application Execution (Service) Installation, GPU detection and Windows XP

Due to problems with up-to-date GPU drivers causing BOINC to crash or hang, it was decided that for all versions of Windows the GPU detection will no longer work when BOINC is installed as a service, or protected application execution. This may change in a future version, but only after the GPU manufacturers have adjusted their driver code. So even in Windows 2000 and XP you can now no longer install BOINC as a service yet still have it detect your GPU(s) and run work on it. This change is present from 6.12.38 onwards.
