No I avoid doing that by re-adding all my runtimes by hand from an external hard drive, then reinstall all the gen 4 stuff and python scripts etc completely fresh into the new Poser Pro 2010 folder..
Going to see if I can maybe get a fresh install od Poser Pro in a different location and then move the file where it belongs by hand, if it will install. But that will wait till tomorrow way too tired to attempt it now thanks for the help!
