Hello,
Here now the official (and complete) system requirements in the "FAQ" on Macecraft homepage.
Question:
Are your products compatible with Vista?
Answer:
jv16 PowerTools is compatible with Windows Vista (both 32b and 64b versions). RegSupreme and RegSupreme Pro are compatible with Windows Vista but only with the normal 32b versions, not with the x64 ones.
Support for Vista 64 bit is coming for RegSupreme and RegSupreme Pro in the future.
Thanks to Veera - the "angel" :) of the support desk - for this quick update.
