It looks to me like the source files in vi.lib didn't get updated properly, this is likely related to the VIPM Community vs. NI Tools Network repository issues described in another thread when DQMH 6.1 first released. I suggest the following procedure:
1. Uninstall DQMH 6.1 via VIPM (all 5 packages).
2. Verify the source files in vi.lib were removed properly.
3. Select Tools > Check All Package Repositories for Updates in VIPM.
4. Re-install DQMH 6.1, making sure that you're pointing to the correct LabVIEW install when you do so. When you install DQMH 6.1, make sure that the 'Repository' listed for each of the 5 packages in VIPM is 'VIPM Community', and not 'NI LabVIEW Tools Network'.
