If the new folder of files is supposed to be at C:Program Files (x86)Smith MicroPoser 8RuntimeLibrariesMaterialsXen0Tartan but you don't see it there, look up in the window's title bar and see if there are compatibility files associated with that address.  If you see this icon, click it and it will go to the virtual location where Windows actually put the files.

Vista does this;  I don't know if Win7 does.  It's a security feature intended to keep rogue executables from overwriting software in the program files folder.

If this was the problem, the long-term solution is to move your content libraries out of the program files folder, usually to the shared documents folder.
