Just had a look to see where the info is stored , and it seems to be in a simple text (xml) file called: LibraryPrefs.xml Curious LabsPoser 5Runtimeprefs each runtime entry has the form : as mentioned, easiest option is to make the path: "F:Poser ModelsRT_MayaDollRuntimeLibraries" consistent for both machines OR you can just have 2 (or more) LibraryPrefs.xml files , say LibraryPrefsA.xml and LibraryPrefsB.xml files, one for each machine, then each time you go to a machine you just delete the original LibraryPrefs.xml file and copy LibraryPrefsA.xml or LibraryPrefsB.xml and rename them to LibraryPrefs.xml before running poser (this could be a batch file for ease). Dont know if this made any sense to you (or me ?) but hope it helps Best Wishes
