Installation & Licensing

[#1]

From the installation of Revit it stopped loading on my pc for no reason. 

After reinstalling it twice still the same issue. when I load up revit the window opens up but this Licensing error 30:failed to AdLM appears 

I ask you why this has happened and how to put this right. It is obvious a licensing issue.

My computer is windows vista and the programm is Revit 12 Architecture. 

Any advice would be greatly appreciated, thank you

Welcome to the community Vale!

Have you tried a clean uninstall yet? If that doesn't fix it, you might want to consider looking into some common 3rd party (non-Autodesk supported) applications which were used in this forum post to resolve the same error 30:failed to AdLM.

Please accept as a solution, or reply with additional specifics if the problem persists.
