Does PDF Architect support XP SP3? (sorry if dup.)

I have XP SP3 on an older PC.  I have installed PDF Architect several times, including latest version.  Installs OK, but on execution I always get an MS Error: "PDF Architect Application has encountered a problem and needs to close."

Details: AppVer 1.1.83.9982
Offset 00084792
Exception: 0x00001d
