I am having the same problem. My operating system is windows vista 32 bit and I am trying to download revit mep 2012. Please help.
I installed revit 2014 with w8, I tried to delete the directory recommended or repair the program, as suggested in the discussion, but it keeps giving me error!
Win8 is a little more strict in its privileges.
I have the same problem with the failure message "licence 30".
I already tried to uninstall et install and I tried to use the repair function but it didn't worked neither.
My computer is running with windows 8, 64bits, what can I do to fix it?
For no reason everytime I try to open 3ds Max or any of the software that came with it, this message comes up, "The software license check has failed. Error 20". I have tried reinstalling the software but nothing has changed. I am using Windows 8. Can you please help?
