Running a VB6 program from CD. Is there an overhead?

I have created a small application that will be used as an installation program. It basically:

1. Copies various files from CD to disk
2. Runs an Installshield program
3. Starts the Network Connection wizard
4. Runs several other programs.

The idea is that my program, the files and other programs will be delivered on a CD and my program will run the installation of the new software. In the code, the copies and programs are run using the Shell command.

With the other programs and files on the CD and my .exe program on the C: drive, this works fine.

However, when I run my program from the CD, the Installshield program freezes at 99% of the file download. If I then cancel my program, Installshield continues normally. Also if I run the Installshield program from the CD in Explorer, it also works without a problem.

It seems therefore that there is some overhead when running the VB program from a CD. Any suggestions would be appreciated.
