I have something interesting, which falls right into this thread.
Setup - Installed Creo 2.0 onto my initial hardware. I went in to the registry and exports the Creo portion, as you noted in your PlanetPTC session. I zipped up the entire Creo 2.0 installation folder, for the purpose of copying to other machines.
Scenario - I have copied the Creo folder bundle to the exact same location as the original installation. Before I merged the .reg file, I launched Creo, and it lunched fine (some window about the start-in location, but ignored that for now). To see if the installation would reconfigure, I followed the process you laid out to be able to do a reconfigure/uninstal.
Note - I added the Help in afterwards on the new machine, which wrote to the registry, as normal. (this comes into play in a sec)
Issue - When I attempt to reconfigure Parametric, Simulation or Direct, the GUI comes up, but there are no "Applications to Customize", which makes me think that the regisrty entries aren't being recognized? However, it gets interesting in that when I attempt to reconfigure the Help (which was installed, rather than copied), I also get an empty list?
Any ideas? I would have at least expected the Help to be availavle, since I installed it the general way.
Any help is appreciated,
****Update- I was able to "reconfigure" my install, if I ran "setup.exe" from the original software bundle. Does this mean that "reconfigure" actually worked? - NO...looks like the setup.exe bypassed it, but at least I was able to update the existing configuration, which it found by looking at the registry entries I had merged back in. I am going to report this to PTC as I am very confident this a bug.
