"The program don't support the project"

Good, yeah when I installed windows 10 fresh on this machine, it gave me a generic eight bit color driver. It was infuriating because I needed to install the network driver so it could search for drivers. That was a real pain. Because the resolution was lower than 400 and I couldn't see anything. Finally I gave up and I just rebooted and it appears that it found the real driver in there somewhere and applied it. But I was worried for a second. It's normal for windows 10 to come up with some generic driver at first just reboot and it should apply the real driver the next time. The only drivers I had trouble with were my brother laser printer and my old HP scanner, both of which I had to use windows XP drivers for under 16 bit mode. Which is "NTVDM" in Programs and features.

I have spent several hours today performing a clean installation and am pleased to report that I no longer have "The program don't support the project" message!

The culprit was definitely something to do with CIR. I was having a look through the driver CD I used to install the graphics driver after my original in place upgrade and when I clicked on one of the files in the CIR folder a little box appeared saying "Notify ... The program will not support the project!" Quite why that became altered to "don't support" when it appeared on the desktop at startup, or for that matter what it means anyway, I don't know.

Unfortunately the clean installation would not accept the graphics driver from the driver CD which surprised me because the previous in place installation was perfectly happy to do so. However I eventually managed to obtain a driver from catalog.update.microsoft.com and installed that instead, which has given me the correct 1280 x 800 resolution.

Right, now I need to get round to copying back all my personal files, which I stored on OneDrive prior to doing the fresh installation. And then reinstall various programs such as MS Office, etc. After that I can at last concentrate on getting to know Windows 10. :)

Many thanks to everyone for their help.

Yes👌

Good work and thanks for posting the update!
