Start by deleting the C:\ProgramData\Flexnet directory (hidden) and reinstall.  There's been some luck with that. 


Otherwise, I'd do a search for Error 20, since there have been a lot of posts about it.

i deleted that flexnet directory. when you say reinstall! reinstall what? I presume your referring to max reinstall?


and im sick of searching and trying things for this error 20 bug issue. Maybe it's related to 2012 on purpose?

It worked. Had to stop the flexnet service before I was able to delete the directory. I did not have to reinstall 3ds Max.

I followed Travis Nave instructions. The directory is hidden, but accessible by specifying it in explorer's address bar. What I added was stopping the Autodesk content management service to allow you to delete the directory. I am using Windows 8.1.

I spent an added day reading through my other programs literature to make sure this would not affedt my pipeline. Then I followed the instructions to delete the files inside the Flexnet folder. (First I stopped the service.) Watching this folder during Max start up new entries were created and there was Max,

Incidently you can see the hidden file from xplorer by view and check unhid (hidden),


Thanks most graciously.
