I have recently had a workstation, that had ACAD2011 installed on it, have a motherboard failure. I replaced the motherboard and, sure enough, the software had unregistered itself due to the change of hardware. After trying to re-register, the software now loads the splash screen, but then immediately crashes.
I have tried doing a clean install as per the instructions on this site, I have run the application as a different user with administrative privileges and also tried to run it in safe mode, all to no avail. I experience no errors when installing/uninstalling the product and an older version of AutoCAD is still working without any issue.
If anyone could offer assistance regarding this issue, it would be greatly appreciated.
Try deleting the file named CascadeInfo.cas.

I tried this, but to no avail.
Are there any other steps I could try to resolve this issue?
I FOUND THE SOLUTION!!!
First of all you need to uninstall every version of AutoCad you installed before, and delete every file that is associated with AutoCad, that means and those files that are located in Regedit, here is a link how to do uninstall all that and delete all these files:
And then after you uninstalled everything and deleted all files, you install your latest version and everything works.
