How to erase profile curve?

I installed “NOWhiteGCO-Curves” by drugging all of the files to “4880-7880-9880-Pro.” but I would like to ease them all.

I drugged them all back to the original file and restarted all, but they were still at the drop down selection. I reinstalled the softwares, but they were automatically installed.

I am wondering how I can erase them all. I am also wondering what the right way to uninstall the Piezo software.

Thanks advance,


Please read this:

It’s also in the manual you have.


Hi Walker,

I removed the curves as the link says. I was also wondering where i can find the document to uninstall the software, both QTR and Piezo software?
