I recently had to reinstall BOINC for Windows 7 X64, and on the third step of the install I clicked on Advanced, then checked Protected application execution. As a result the BOINC startup messages always said that no useable GPU had been found. I suggest that the wording of the message during installation is misleading. Here is what it says:

"Run project applications under an unprivileged account. This provides increased protection from faulty applications, but it may cause graphics to not work with older applications, and on Windows Vista, it will prevent the use of applications that use graphics chips (GPUs) (A reboot may be required.)"

Since I wasn't concerned with graphics working, and I use Windows 7, there was no obvious problem. Perhaps a rewording is in order?

It's on Rom's ever growing To Do list. I had alerted him of the same thing a couple of weeks ago, but thank you for your hint as well. In future, assume that when it says Vista, that it's Vista+, meaning everything after Vista as well. ;-)
