I am trying to install Sinumeric DocOnCD 2015 onto my computer.  I have installed several previous versions over the years and have had no issues until now.  

The installation progresses through the question portion and proceeds to the installation portion of the process.   Then it halts and gives a file not found alert.  The file it is looking for is \data\32BitLauncher.exe.   If i browse to the directory on the disk there is a \data\32BitLau.exe file.   If i copy the disk to my hard drive and edit the filename in question so that it matches the expected value then restart the installation process from my hard drive, the installation proceeds, but then alerts on another "misnamed" file.  This fix and continue process was attempted until I could not figure out what file to rename.

  It seems that the disk has 8.3 filenames where the installer is expecting long filename support.   A coworker in my office has installed this onto their system with no issues, so I don't think that it is a disk problem.  We are both on Windows 7

Suggestions?

Coworker and I have Identical computer setups. Win7 64bit, same antivirus, windows firewall, both administrators on our respective laptops.  Cannot turn off antivirus.

I tried installing both from the DVD and after copying the DVD to the harddrive.  Same results. 

I was finally able to install it by hooking up an external DVD drive, then the filenames appeared correctly.  I must have installed a piece of software along the way that affected my internal DVD settings somehow, because it was only had the 8.3 filename support.   Now, I have to figure out what software caused this....

Thanks for the assistance.
