We just upgraded our test server from 7 to 8.  The upgrade seemed to go fine, and our test sites are working.  Toward the end of the upgrade process, the installer took me into CF Administrator, which worked fine.  After the installer completed, it told me there was a previous version that should be uninstalled.  I went in and uninstalled it and then rebooted.  The sites still work, but I cannot get into Administrator.  The CFIDE folder at the root is missing.  I assume the uninstall of 7 zapped it.

So I do have CF 8 on a production server, and I thought I would just copy it over.  Once I do that I am getting an error:

500

ROOT CAUSE: 
java.lang.NoSuchMethodError: coldfusion.tagext.GenericTag.doFinally()V
     at cfApplication2ecfm1253482620._factor7(E:\cf8_updates\cfusion\wwwroot\CFIDE\administrator\Application.cfm:4)
     at cfApplication2ecfm1253482620.runPage(E:\cf8_updates\cfusion\wwwroot\CFIDE\administrator\Application.cfm:1)

There is more after that.  The strange thing is those "at" lines.  It references e:\cf8_updates.  The production server has no E drive at all.  The test server does have an E, but there is no CF8_updates folder.  I installed CF8 from the D drive, so I'm not sure where the reference to E is coming from.  This is a Windows Server 2003 using IIS 7.

Thanks in advace,
