I downloaded autocad 2018 ...my system is 64 bit...I downloaded everything from the setup app and then auto launched it. Then the app initializes, loads and then this error pops up. Please help...

Hi,

 

You can try:

  • start AutoCAD as administrator (right-click the AutoCAD start icon and use "start as administrator" in the context menu
  • create a new WIndows user account and see if AutoCAD starts in that context
  • start AutoCAD without hardware acceleration (using /nohardware switch) as described >>>here<<<

 

Good luck, - alfred -

PS: You can create screenshots directly in Windows, not need to make a photo from your monitor and then make a photo from your handy 😉

I've been seeing similar issues being caused by the latest Windows update and .net framework 4.7. Can you confirm what version of .net framework your system is running?
