[Bug 21557] New: .net 3.0 redistributable installer aborts after clicking 'OK'

http://bugs.winehq.org/show_bug.cgi?id=21557

Summary: .net 3.0 redistributable installer aborts after
                    clicking 'OK'
           Product: Wine
           Version: 1.1.37
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Keywords: regression
          Severity: normal
          Priority: P2
         Component: wintrust
        AssignedTo: [e-mail]

says "winetricks dotnet30" works but says there is a "large delay near 
the end of installation".  This seems to be true with wine-1.1.31,
but with current wine, it aborts after a few seconds instead.
Looking in c:/users/$LOGNAME/Temp, I see dd_dotnetfx3error.txt which says
[01/30/10,16:19:12] XPSEPSC x86 Installer: [2] Error code 1603 for this
component means "ERROR_INSTALL_FAILURE"
and dd_XPS.txt (?) which says STR_FAILED_INF_INTEGRITY.

Could this be the same regression as bug 21542?
