How Downgrade CVI-RTE from 8.5 or higher to 8.1?

[Jagger_HKG]

Hello at all,

I have update the Device-Drivers at a "old" One-Core-Processor-PC.

By this unfortunately the Run Time Engine was updates to Version 8.5 automatically.

My problem is, that this old PC with One-Core-Processor losts a lot of Performance with RTE Version 8.5 (that is optimize for Dual-Core-Processors) and the CVI-program doesn't work robust enough now!

How can I donwgrade the RunTimeEngine to 8.1 so simple as possible???

Thanks

It seems the simplest solution would be to uninstall 8.5 and reinstall 8.1 being carful no to update it.
