How do you extract .msi files from setup.exe's?

[Python007]

This is my first posting on here, so i'll say a big HI to everybody

i'll get straight to the point, because I'm sure someone, such as 'Cueball' can help me here...........

I've read the 'Call Of Duty' CD-2-DVD conversion thread, and big thanks to 'Cueball' for supplying the .msi........

My question to 'Cueball' is - did you extract the .msi file from the Setup.exe file?

If so, how did you do it? - I have looked for some sort of program to do this, but i'm either looking in the wrong places, or I don't know exactly what to look for!

If not, then I presume the .msi was created from scratch - can you provide any pointers, so that I can maybe have a go at creating my own .msi

The reason why I'm asking is - because I have done the CD-2-DVD conversion on a game called 'Perimeter' and want to patch the .exe on installation BUT, although this is successful, I get the CRC error, when the installer comes across the .exe (the one with the Abort, Retry and Ignore message)

The game executable is visible in the CD's root folder, and the data1.cab/hdr etc points to it's location BUT the file is not visible when you list using i6comp (a ghost file?)

I remember coming across this when converting my GTA vice city to DVD too, where the gta-vc.exe exists in the root folder.

I did read a spanish site, where someone used i6comp to add the gta-vc.exe file to the 'File group' (57) using i6comp i.e.

i6comp a -g57 data1.cab gta-vc.exe

BUT, I tried this on Perimeter (the App Executables group is 31) (i6comp a -g31 data1.cab Perimeter.exe) - and it did not work

I tried using winpack and deleting the file group to re-create it but it did not even delete the old file group!

I would love to know how to extract .msi's from setup.exe's (if that's how you do it)

Sorry for the long post - I hope someone takes the time to reply and help me out.

Thanks
