The newest version now works for me with Sound pack B.  Thank you!

I noticed something that seems odd to me...

If you look at the error message, there are two backslashes after the 'D' and before the 'DriverPack' toward the end of the error message.

Also, if I look at the file structure of the $OEM$ directory that's located in my target directory, I have:

$OEM$\$1\D\D\S\

then directories with names like Y, TR, T, SM, and so forth.  Should there be two D directories after the $1 directory?  Just curious...

I first get an error box titled "Critical Error" that says:

Failed to CAB compress c:\download\XP_Driverpacks\tmp\DriverPack_Sound_B_wnt5_x86-32.ini to C:\download\SP2+\$OEM$\$1\D\\DriverPack_Sound_B_wnt5_x86-32.in_.

I can click OK, then get a second box saying that the temp directory can't be deleted...and it hangs.  I can click OK repeatedly but the box keeps reappearing.  The only thing that will end the program is to 3-finger salute, Task Manager, then select the process and end it.

I looked at the log file, but it gives no further detail other than the above message.

The answer to your (and my) problem may end up being reported in this thread:

Same problem here, with the Sound Pack B and using Method 1.  Since that's the method that does what I want, I suppose I'll have to wait for a fix...
