I have the same problem (albeit the end number is 26, not 2) but there is no 'adlm' folder and therefore no 'ProductInformation.pit' file to delete.
Any other suggestions? Please, I miss my Autodesk!!!
Cleaned with regedit
removed InstallMicrosoft Visual C++ 2010 SP1 Redistributable
Removed files from any inventor
Still I get the same error and can't install CFD or Inventor software.
