user.lib conflict

[PTC_NI_Dude]

Using LabVIEW 8.5.1, I am trying to load a project which an outside developer and I have been working on.  All the vi's and other files are bundled into an .LLB file which I retrieve via FTP.  The problem is that the developer has a set of driver vi's which we have been trying to debug stored in the .LLB.  On my system, driver vi's with the same name and general functionality, but which may or may not be the same, are loaded in my "user.lib" folder.  Of course, when I try to open the project, I get conflicts.  However, the "Resolve Conflicts" dialog locks the files so that I cannot remove the duplicates.  Also, I can't seem to remove "user.lib" from the dependency tree.  I want to use his driver vi's, not mine, but can't figure out how to do it.  Can anyone help?

I would suggest using project libraries instead of LLBs. Project libraries qualify the names of VIs by prepending the name of the library, avoiding cross-linking. Another possibility is to change your VI Search Path to force it to look for files in a specific directory before any other place. You can change the VI Search Path from your LabVIEW options dialog.
