Unable to install LV Runtime Engine 7.1.1 with LabVIEW Professional 8.5.1

[auctoron]

I installed LabVIEW Professional Sys. for Windows (XP) 8.5 and then the 8.5.1 update. Somewhere in the original installation, LV Run-time Engine 7.1 was installed. But I need LV RTE 7.1.1. So I attempted to install RTE 7.1.1. Problem: The LV RTE installer aborts with the following message:

"Installation aborted. Newer version already installed." 

Why do I need 7.1.1? I must run some commercial LV executables that were compiled with LV 7.1.1 and will not run under 7.1.

You may have to uninstall RTE 8.5.1 to proceed with the 7.1.1 install and then reinstall RTE 8.5.1.

I hope this helps!

Well, I have to correct myself. MAX indicated that LV RTE 7.1 (not 7.1.1) was installed. My complied LV app indicated that 7.1.1 was not installed. I checked Windows Add New Programs and selected "National Instruments Software" I found that LV RTE 7.1.1 was, in fact, installed. So I selected LabVIEW Runtime Engine 7.1.1 and clicked Repair. After rebooting, My app works correctly. Again, MAX incorrectly displays LV RTE 7.1 (not 7.1.1). My app works, so I don't care.
