Thanks all. I have found a major problem with the program logic. I downloaded a new prop that uses yet another format of specifying texture location. I have rewritten the code and am testing it now. It will work for Poser installed on any drive. You need to change a small configuration file to point to the poser folder. If a file is fully qualified i.e. F:xxx.xx.xxx it will be checked, relative references check ...runtimetextures libraries.
