Uninstalling Run-Time Engines

[rmtripp]

How can I manually uninstall extraneous LabVIEW pieces from my Development system that were generated when I used (not knowing better) my development system to test my installers?

This has led to problems with the Application Builder.  If under Additional Installers I uncheck any of the options under LabVIEW Run-Time Engine 2010, the Distribution title changes from "Local Cache" and the Installer source location from "C:\Program Files (x86)\National Instruments\Shared\ProductCache" to locations referencing some of my programs.

I have been informed that the problem is probably due to having Installed the installers, but no one has come up with a method of cleaning out the extraneous Run-Time Engines short of reinstalling Windows 7 from scratch -- which is not an option.  I have uninstalled LabVIEW, run msiblast and msicuu2, then reinstalled LabVIEW 2010 and still the problem remains.

Hi rmtrip,

I found this discussion form that deals with unistalling the 8.5 runtime engine. While you are using newer software it might be worth trying some of the the suggestions.

Let me know how it goes.

Most of the info was not relevant, but the mention of the fact that the LV runtime engines have an extenson of .msi was useful.  I did a search on LV*.msi and found 206 entries -- which may be my problem.  I will go through and use the uninstall associated with at least some of them and see if that helps.  Thanks for the pointer.
