If you continue to have upgrade and/or uninstall problems, our
installer guru suggests the following:

Go to Add/Remove Programs, select NI-VISA 2.5, and try Repair and then
Uninstall.  After it is uninstalled, then you should try upgrading to
3.1.

For most folks reading this, these steps aren't necessary.  Somehow
your system got into an odd state, and hopefully the Repair should
bring it back into a stable state.

I'm not sure why you can't uninstall 2.5.  But the version of NI-VISA
you want to upgrade to is 3.1.  We've fixed a lot of serial bugs in
each release, and gotten rid of a lot of incorrect
VI_ERROR_SYSTEM_ERROR return values (some are fixed, others are
changed to more logical error codes).
