I was running Nero 9 alone and ran into a wierd problem with just the DiscSpeed application, it could no longer see my USB drives only ATA. All the other applications in Nero and other could see the drives no problem.
After hours of troubleshooting I uninstalled Nero 9 and reinstalled Nero 7 but only the Burning ROM application. This fixed whatever setting or DLL problem and DiscSpeed worked fine again.
So I installed Nero 9 again but did not think to uninstall Nero 7 since in the past it usually prompts me to uninstall but it did not this time. I now have Nero 9 (full install) and Nero 7 (burning ROM only) running side by side and so far they seem to both work fine.
I noticed in the registry and under Program Files, there are completely separate trees and directories for both.
So has anyone else tried this without issues?
