In Dec 2015 I asked Roy Harrington if QTR download might be a problem, I was being forced so to speak into upgrading to W10. His answer at that time was; “Win 10 works except for Curve Create but you don’t need that for Piezo as the curves already exist. So install as is (on W7 which I used at that time), install again when you upgrade to Win 10”.
Thanks Brian for the links, from which I understand that Roy had recently uploaded a fix for Windows, and that the PC version is now 2.7.7
In the meantime I still have the older version (downloading 2.7.7 still not successful) without updated/current curves, I’ll probably drag and drop the ones I’m interested in.
I certainly appreciate efforts by the experts to make things work.
