And as for a possible 64-bit version of XY, the following snippet, emphasis added, of the News is interesting:
I’m pleased to announce the availability of Attribute Changer 9.10. This version features a significant technical change that will impact all future releases of Attribute Changer.
In fact, Attribute Changer was developed since the beginning in Delphi, but the direction taken by the new owner of this product makes it no more an option for the development of Attribute Changer.
Version 9.10 is now developed using Lazarus/Freepascal and so will be all further releases. The shell extension has been converted from C++ to Freepascal.
