The problem you are experiencing is a previously installed program (Smartsound) left trace files in the Microsoft Installer program.
The trace files are being triggered when our software attempts to use the Microsoft Installer and they are prompting you for a disk to reinstall.
The issue will continue each time our software is started until it is properly dealt with.

You can solve this problem by putting in the disk for the other program when you are prompted to.
If you don’t have the disk, one option is to go into Windows Control Panel and uninstall the software that is attempting to install again.
A better option would be to install and run the Windows Installer Cleanup Utility. It is a Microsoft utility which will remove the trace files without harming any software installs.

Below is a link to download the utility.

Run the install of this Microsoft Utility.

After it installs you will need to go into Start->Programs->Windows Install Cleanup to run it.
When it comes up it will display a listing of software packages with trace files left behind in the Microsoft Installer.
Locate the program that is giving you a problem.
Click on it to select it and choose Remove. Do not remove any other items in this area accept for the specific program that is causing problems.
This process does not affect the installed programs; it just removes the file traces causing this issue.
