I have several autodesk products installed on my computer, all 2012, and none will run.  They all ran when installed them a while back but now they all give me licensing errors.  How do I get around these problems and what is causing this?

the products are:

Autocad mechanical 2012, 

3Ds Max 2012,

Inventor 2012, maya 2012,

Mudbox 2012.

Revit Acchitecture 2012.

and several more smaller programs

Hi Rick,

 

Looking through the Discussion Forums, I was able to find a couple of relevant threads that might be a good starting point.

Specifically,

 

As Licensing is almost the same for most Autodesk products.

You can also try to add license service exe(C:\Program Files\Common Files\Macrovision Shared\FLEXnet Publisher\FNPLicensingService64.exe) to DEP exceptions (http://www.online-tech-tips.com/windows-xp/disable-turn-off-dep-windows/)

 

Close the application, then delete the casecadeinfo.cas file located in the following directory and try running again:

Windows 7:

C:\ProgramData\Autodesk\AdLM\

Windows XP:

C:\Documents and Settings\All Users\Application Data\Autodesk\AdLM\

 

Another user posted that a system restore resolved their issue.

 

Please let me know if any of this helps.
