Then you need to determine what it is on your machine that changes that breaks the license.  Maybe Windows Update, or Anti-Virus, or some other domain change.  In any case, do some research and create a restore point to see if going back to a certain date when it was working will be a suitable solution for you.

Do you have this problem only with Inventor or other AutoCAD based products as well ?


If your cascadeinfo.cas file is getting corrupted, it might be due to some Windows corruption.


However can you confirm whether you can launch products in diagnostic mode when the problem appears again.


I just want to isolate and see whether the problem is really with the corruption of this file or with any product conflicts in your system.


Also, please send us your system information file for us to investiage further.

The solution of my problem occurs to be much more simper. It turns out, that FLEXnet Licensing Service was turned off. I don’t know why it was turned off, but after turning it on Inventor starts without any problem. Thank you for the link with information about this service.
