What do you mean "fixed"?
From what I have discoverd, the pack-it.exe modifies the system resources with the Vista images.
I think this is how the packs work.
First, all the system32 resource files are copied to:
C:\WINDOWS\BricoPacks\SysFiles
Then, using pack-it.exe the system resources are edited..
[I think pack-it uses ResHack, found in C:\WINDOWS\BricoPacks\Vista Inspirat 2\ResHacker, and the ResHack scripts and the icons (found in C:\WINDOWS\BricoPacks\Vista Inspirat 2\ResFiles) to modify the files].
CODE[FILENAMES]
Exe = "TempFiles\desk.cpl"
SaveAs = "PackFiles\desk.cpl"
Log = "TempFiles\desk.cpl.log"
[COMMANDS]
-addoverwrite "ResFiles\13_desk.cpl\BITMAP_120.bmp", BITMAP, 120,
-addoverwrite "ResFiles\13_desk.cpl\ICONGROUP_40.ico", ICONGROUP, 40,
-addoverwrite "ResFiles\13_desk.cpl\ICONGROUP_100.ico", ICONGROUP, 100,
That code was an example of the ResHack scripts. So, first the desk.cpl is taken, then the commands are applied (which icons to add, etc.) and then it is saved into PackFiles folder.
This is how I think it works 
(so I am not sure)
* and by the way, how would your fix for Packit.exe work?
