Thanks for pointing me to the right direction. I uninstalled and reinstalled Logger32 -- same problem. The Dell support disk program was trying to write to the Dell support disk, using RCD.MSI, which it could not find without the Dell Support disk. I downloaded the MS cleanup program. It did not show Logger32 as a program it would delete. But it did show Dell Support Disk as a program which could be deleted which I did. Logger32 now loads as it is supposed to do. Any notion of the consequences of deleted the Dell support Disk program?

The cd I am talking about is p/n kd016 rev.A00. The title is Dell ResourceCD. It is intended as a disk on which one boots the machine to deal with device drivers, diagnostics and utilities. The legend says the software is already installed on your computer. Only use this CD to reinstall the software. I accidentally reformatted my whole raid array and had to use this disk to help the recover process. I thought I knew something about computers. As it turned out, I knew just enough to be dangerous.

Yesterday, I used the diagnostics on that disk by booting from the disk. They check everything including the memory and hard drives. It takes forever. I finally had to terminate the tests after 6 hours of testing and 80% finished. It did discover one device on the USB bus that was not working properly. Using this disk in the way prescribed had no effect on initiating the Logger32 program. I think the computer was just confused by the combination of the two programs. Now that the program calling for the disk is gone -- no more problem. I don't think I will again install the program that calls for that disk. I think I'll keep the disk for the diagnostics. I wonder if I will ever have time to use them. Thank you for your advice and guidance. You have been wise, patient and helpful. If I have the opportunity I will help others as you have helped me.
