In order to reply your question from the subject - our readme.txt says 
so as far as I can see. ;-)

 From a technical point of view - yes, GetTickCount64 is indeed not 
supported before MS Windows Vista (thus not available in WinXP). While 
this API should be preferred over GetTickCount whenever available, 
providing a fallback for systems not supporting GetTickCount64 natively 
is obviously quite simple / easily doable (load GetTickCount64 
dynamically rather than statically at startup and assign a local 
function falling back to GetTickCount to a GetTickCount64 procedural 
variable in case the dynamic loading attempt fails).
