Yes we have tried Caspol.
Don't usually have much of a problem with XRL as long as the UAC is off and the user has local admin rights it usually works.
Customer has been using v1.47 and we have been upgrading them to v1.63. The only PC it has worked on is the Windows 10 PC with Excel 2016 (with a new LsDatabase).
We've had to revert the non-working computers back to v1.47 so at least they have something.
