Multiserver option not available during ColdFusion 8 Enterprise install

The option to select Multiserver Configuration is disabled during an Adobe ColdFusion 8x Enterprise installation.

This issue may occur for one of the following reasons:

There is an existing installation of ColdFusion MX7 or ColdFusion 8 multiserver (you have a /jrun4 directory on the machine).
Your system has some lingering ColdFusion or JRun Windows Registry keys even after you successfully uninstalled of a previous version of ColdFusion or JRun. This could occur if you tried to apply the 8.0.1 updater but forgot to stop all instances of ColdFusion/JRun before hand.

Delete any folders on the hard drive named "jrun4".
Choose Start > Run, type regedit in the Open box, and then click OK.
In the Registry Editor, create a backup of your current registry by choosing File > Export, entering a file name, and then click ling Save.
Search for any ColdFusion keys by choosing Edit > Find, entering ColdFusion in the Find What box, and then clicking Find Next.
Delete leftover or unnecessary keys by pressing Delete, and then press F3 to go to the next search result.
Repeat steps 4 and 5 using JRun as your search string.
When finished, close Registry Editor and reboot the server.
Re-run the ColdFusion 8 Enterprise installer. You should now be able to select the Multiserver configuration option
