I've (sadly) "mis-installed" LabVIEW numerous times (usually when trying to install two or three versions all at once -- I forget to do "oldest first", or otherwise put something in the wrong place).

Isntallation order of LabVIEW versions should not matter. Why do you think it does?

Hmm -- I have some applications that use LabVIEW 7.0, but am developing my own stuff mainly in LabVIEW 8.6 and 2010.  I do seem to recall several (all?) earlier attempts to install 7.0, having an existing 8.6 installation, and getting some sort of failure.  So I was all prepared to (smugly) demonstrate the LabVIEW "I Can't Do That, Dummy" message here ...

Not wanting to mess up a perfectly good machine, I cloned a VM running 2010 (on Windows 7) and tried to add 8.6 (which, as we all know, won't install on Windows 7 unless you know the trick).  While waiting for the error box to appear, I got (instead) "The LabVIEW 8.6 installation is complete".  Ha, gotcha, Bob!

Well, maybe my memory is just faulty, or it's a Windows XP (or older LabVIEW version) thing.  Anybody else been bitten by the out-of-order "feature" in installing LabVIEW?

The only known incompatibility where installation order matters is with the the LabVIEW runtime 7.1 and 7.1.1. (See the last post in this thread)

What's the 'trick'?

For some reason, running "Setup" from the root of the DVD (which is what Autorun does) bombs out under Windows 7.  However, if you open the DVD and look "down" three levels into Distributions\LabVIEW\LabVIEW860 and run the Setup that you find there, it will install just fine.

For those who are interested, and especially those who can't actually access the appropriate parts of the control panel due to user account privileges, there actually *is* an NI-provided uninstall utility.  However, it doesn't actually install on your computer like one might expect.  Instead, it's on the installation discs.

It's buried several layers deep in the directory structure, though, so just toss the disc in your drive and search for "NIUNInstaller.exe"
