I recently started having a problem launching Nortel’s Java Device Manager on my Windows XP desktop. Upon launching the application nothing would appear on my desktop but I could see the “java.exe” process in Task Manager.
I tried uninstalling the application but the uninstall appeared to hang toward the end as it was cleaning out the registry, I eventually had to kill the uninstall process. I even tried installing the latest and greatest version only to be denied at every turn. Then I recalled that the application liked to keep a list of recently accessed switches and settings somewhere on the hard disk.
I found the location under “C:\Documents and Settings\
I was fearing the dreaded Windows re-install, thank god I didn’t have to go through that!
