(Feb 2003)
When LabVIEW 6.0i was released there were several issues with the installers for LabVIEW and its drivers. This was such a nightmare that several of the team working on this wore t-shirts with "we know the installers don't work ..." at NI Week 2002.
The solution:
1. Execute regedit or regedit32 depending on your platform (ie Start/Run, type regedit32, OK).
2. Do a search and find the following section in the registry: HKEY_CLASSES_ROOT>>INSTALLER>>PRODUCTS w
ith the value of 20F22BE295933D11082B000540F95DD5
3. Delete the TRANSFORMS field.
4. Exit regedit.
5. Try the uninstall again.
6. Ignore the laughter of the MAC only LabVIEW users.
