1) No idea! We have no relationship to PowerArchiver and we OEM SPTD stack from DuplexSecure pretty much like P/A guys. Contact any of them (both?) to address your issue but either way it's not our one. Sorry about that

2) Nope. Most recent version of StarBurn / SDK support Windows XP as well.

Why does PowerArchiver still install SPTD v1.81 when installing the PowerArchiver Virtual Drive even on Windows 10? PowerArchiver includes both PABURNER16.DLL v13+ for Windows Vista or later and STARBURN.DLL v12 for Windows XP. Is STARBURN.DLL v12 the last version that supports XP.
