It took two days and a couple of additional suggestions but I was able to get it fixed. Whew!
For two days, I repeated the suggested clean reinstall multiple times with different versions of the DESKTOP software. I tried V2.2.2 through V5.0 to no avail.
Note that I've been concentrating on the DESKTOP software all this time because I couldn't get the installation completed. The missing "Blackberry 8310.msi" message kept popping up.
A suggestion was made at the RIM forum that I should also replace the Blackberry DEVICE OS.
So on the next iteration, I tried deinstalling the BB 8310 DEVICE software from the Control Panel. While doing this, an error message popped up saying "The configuration data for this file is corrupt." The Device software disappeared from the list of installed software in the Control Panel though.
I tried to install the DEVICE OS a few times but I kept getting the "The configuration data for this file is corrupt." error message. Using Daphne's suggestion above, I downloaded the Windows Installer Cleanup Utility.
After removing the Blackberry device OS with the Windows Utility, I tried installing the Device OS again. This time it completed the installation without the error message.
I launched the Desktop Manager software (V5) and voila!!!! It works. Hallelujah.
So, it was the DEVICE software all along that was hammered by the ungraceful shutdown and not the DESKTOP software.
A few things I learned during this process:
- Blackberry 8310.msi is part of the Device software. During installation, a message flashed on the screen saying it is exporting Blackberry 8310.msi.
- If the Desktop software doesn't connect to or have the connection port show up for the blackberry, it is likely that the Device software is corrupted.
- Got to learn how to use the registry.
Thanks. I hope the account of my experience above helps.
