I'm sure this is a good one. I was trying to install AutoCAD 2015.
I have two computers, a Windows 8.1 desktop and a Windows 7 laptop. R2015 installed flawlessly on my desktop.
My laptop has AutoCAD versions 2008 thru 2014 installed. I keep old versions so I can test VLisp routines.
The 2015 install crashed with the popup message of “1: 5 2: adlmPITSetProductInformation failed 3: 2”. Apparently this means there is a problem in the License Manager file "ProductInformation.Pit". The return error is #1603.
AutoDesk had me uninstall all AutoDesk products and then delete the Pit file. They all uninstalled except for AutoCAD 2011. It popped up with the same “1: 5 2: adlmPITSetProductInformation failed 3: 2” message. So I used the Microsoft's Fixit Uninstaller and it claimed 2011 was uninstalled. It left the C:\programs folder full of files however. I then deleted the Pit file.
Then I installed 2015. It installed perfectly and created a new Pit file. Hurray!
Next I attempted to reinstall R2014. It crashed but without the same popup message. However, the log file indicated the same error of #1603.
I'm stumped. I just wish there was a utility to wipe the computer clean of all AutoDesk software so I could start fresh.
Anyone else ever have this happen?
Thanks
