We found a issue when to registry components by regsvr32.exe on Windows Vista Beta2 Building 5344.winmain.060316-1340 (free build), pop-up a dialog box with following message,
The module "DllRegisterServer" was loaded but the call to C:\Users\xxx_5344_FreeBuild\Desktop\test.ocx failed with error code 0x80040200.
Any comments will be welcome, thanks in advance!
BTW, there is no the issue on previous builds and 5344 (debug build).
