AutoCAD LT Launch problem

[sergej_dezelak]

I have problem when I launch AutoCAD LT, I got this message (image LT1). It apear only when I first launch my PC, if I restart PC, than it is ok. I use Windows 8.1.

Second problem is (image LT2), this message apear at launch AutoCAD LT. Do you think it is problem only with graphic card?

Not sure when else can be said about image LT2. It pretty much says it all in the dialog. Your video card does not support hardware acceleration.

Your first message appeared because, according to it, you ran a Windows Registry Cleaner in WIndows. Or an application on your PC did. AutoCAD didn't do it, it's just letting you know that's a probably cause.

The second message appread because your video card driver changed: AutoCD didn't do that either. it's just telling you your system change is changing how AutoCAD uses your system.

So what changed a month ago? find out, even Windows will tell you.
