I need to downgrade a USB TC-01 to work with an older windows 7 computer.

I need to downgrade a USB TC-01 to work with an older windows 7 computer. It was already upgraded to work with a window's 8 Machine. I need firmware version 1.0.0.f1. I can find a firmware UPDATE utility but not a DOWNGRADE utility. 

Any help?

Hello lhundley42,

I hope this post is not too late! Unfortunately, it is not possible to downgrade the firmware on your USB-TC01. If you have upgraded to the latest edition of the firmware then the device will have to be used on PCs with NI-DAQmx driver 14.5 or later. 

We do have a limited number of USB-TC01 modules with the older firmware still installed and available for purchase. The part number for these devices is 784355-01. This legacy device can be purchased here. You should be able to add this device to your cart or talk to your NI Field Sales Engineer if you are interested in purchasing it.
