I installed 2012LT on a HP4430s with Win7 64bit, 4GB memory, Intel CORE i3-2310M CPU @ 2.10GHz & Intel HD Graphics Family Video Card. Started and ran fine for about 2 weeks, then I got a blue screen and have not been able to get it to run since. I have uninstalled (complete including registry); repair; reinstalling in safe mode; removing FLEXnet file; resetting AutoCAD 2012LT settings to default and the same thing happens when I start the program, it appears to load then as it should flash to full screen it does for less than a second then shuts down. Does anyone else have this problem or know of a fix for it? I started with AutoCAD Lt 15 years ago and have upgraded every couple of versions and have never had this kind of problem. Any suggestions or help would be greatly appreciated.
Did you delete your ProductInfomation.pit file as well? Probably a corrupted license.
Could you please find and upload the startup log file with .log extension located in folder C:\ProgramData\Autodesk\AdLM for research?
