"LabVIEW Runtime won't install"

[bluesbros]

Hi Folks,

      Am trying to install LVRT821 on a machine, but it refuses to show-up as installed list shown through \control-panel\Add-remove programs\National Instruments.

Machine had some NI stuff installed already and after first a couple of [unsuccessful] installs/restarts, began slowly removing current NI installations.

Am down to MAX and getting ready to install again (after a restart.)

OS is WinXP and I'm logged-in as an admin, running LVRT installer EXEs downloaded from NI today. (Have tried LVRT82 as well LVRT821.) 

Any ideas?

Cheers!

Problem "solved" by uninstalling all NI SW and deleting \Program Files\NI.

One thing I didn't notice initially -LVRT install indicated LVRT already installed (Leave as-is.)  Regardless, it was missing from Add/Remove Pgms (could not be repaired) and EXEs would not run.

Cheers!
