I did look in the Vue directory but didn't see that teeny 2.7 mg file. I guess my eyes were crossed after looking at all those registry entries. The poser.dll file in the Vue directory is compiled and, for the most part, illegible. I did find many references to poser files and settings but none to the poser.exe path. It probably is in this file--Lord knows everything else related to Poser is (including animation settings)--but is illegible and, of course, uneditable. It seems to me, though, that if installing other software makes it stop working and forces a reinstall, there must be an external link somewhere.
