Proper downgrade procedure from 7.1 to 7.0?

[Whimbrel]

Motherboard died on lab machine running LabVIEW 7.0 vi.  I built new machine, reinstalled all hardware and mistakenly installed 7.1 instead of 7.0, not realizing that driver/dll issues would prevent old VI from running.  So, now I want to install 7.0. 

Do I need to completely uninstall 7.1 and all ni*.* drivers from windows/system32/ first?  Or can I just install into a separate directory and have both versions on the system at the same time? 

Thanks!

You can install 7.0 side by side with 7.1. If you want to use the drivers (DAQmx, NI-VISA, etc) that came with 7.0, then you would have to first uninstall the drivers you installed with 7.1.

Exactly what kind of issues are you having with 7.1. The upgrade is generally painless.
