Greetings from sweden, running free version of OA
Have same problem (or same error report however). Annoying cause error message and windows solution message pops up 5 times before cpu is ready to use..
On startup I get the message that OA Miniport is missing:
1. Verify the correct driver is installed.
2. Try updating the drivers using Windows Update.
3. Check with the manufacturer for an updated driver.
4. Attempt to uninstall and then reinstall the device using Device Manager
Can´t remember that I messed around with my cpu, installing stufff and so on, but perhaps I did some kind of gadget installation...
Well, I read the answer in post #46 and the last post #50.
Please just verify if the solution is to uninstall and reinstall OA, in safe mode. And please give me a little further instructions on how to do that. I know start up in safe mode, but should I first of all download latest version of OA and leave it on my desktop? Any special things I should think of? I have pretty good skills but please give me some hints if necessary.
