Installer runs painfully slow when running off a cd.

[jrhutch]

I have written an installer that copies directories from a cd to the machines file system, and calls another utility of ours that does some sql operations.

Running the installer from the root of the cd causes it to hang during a RMDIR command, and the installer takes about twice as long to complete than if I copy it to the target machine and run it from there. At the end of the install, the installer does a RMDIR /r on a temporary directory, and I can see it delete the files in the detail window, but when it tries to remove the folder, it takes forever, somewhere upwards of 10 minutes.

I have watched the installer in task manager and during this time it uses almost no processor.

Has anyone else had this issue, or know why this might be the case?
