Error 1722 when installing Run-Time Engine 6.0

[smok]

I am unable to install the necessary LabView Run-Time Engine 6.0 required to run my VitalView Software.  I have reviewed the message boards and attempted all possible solutions: disabling anti-virus programs, following the NI support links: http://digital.ni.com/public.nsf/websearch/334E91287EDEA75286256D9B003A947A?OpenDocument.

None of these methods will allow for the Run-Time engine to be installed.  What can I do?

Help very much appreciated, thank you!

And what is your OS ? Windows 98 / XP / Vista / 7 / Linux ? 32 / 64 bit ?

Just remember that 6.0 is a very old version of LabVIEW.

And what does error 1772 say ?

Take a picture and paste it here.

My OS is Windows XP.  

I am trying to install an older LabView run-time engine since my application VitalView asks for a LabView 6.0 Run-time engine (or something compatible). 

I have attached the jpg of the error message that I receive whenever I attempt to install the LabView engine.  

Thank you so much for your help!

Do you have other versions of the run-time engine installed ?

Thanks for the tip!  I went back and uninstalled any previously downloaded files from National Instruments and the installation for the Run-Time engine 6.0 went off without a hitch!

Thanks again for providing a simple solution to my headache!

Gracias!

If you want to have multiple Run time engines on the same PC, you need to install them in the right order. 

Start with the oldest engine.

I'm glad to hear that you solved your problem.
