I had a local installation of ARIS 9.5 on my laptop. I inserted the ARIS 9.7 CD and ran the Set up file. The installation did not complete, an installation error was generated. I unistalled ARIS 9.5 and ran the set up file again. The following error displays "An internal developer version is installed. You cannot update this version. Do you want to unistall now?" I click Next to proceed to do the uninstall. After completion I run the set uo file again to get to the same error. Please advice on what I need to do install ARIS 9.7 on the laptop
