Hi,
Its been two days, i have tried every possible solution i came accross on the internet to fix this error but still cant get the Autocad Electrical to work on Windows 8.1
Solutions i have tried so far
Resetting autocad to original settings
Run without Hardware acceleration
Did clean install 3 times, After removing REG entries, All files and folder, Local Data
Updated Service Pack
Uninstall and re install NET Frame Work
Its driving me crazy, screen shot attached
AutoCAD Electrical 2014 does not officially supports nor fully tested on Windows 8.1 OS being released just few days back. Many a times there needs to be some tweaks required in installer to support the newest OS. We have noted down your case and investigate.
We align ourselves to support AutoCAD listed operating systems in the main product or service pack. Windows 8.1 is a very recent OS release and it is officially not supported.
