Installing standalone CF7 after installing JRun4

[ChipTemm]

I have installed JRun4 in developer mode. Subsequently I am attempting to
install CF7 in "Multiserver configuration" but this option is dimmed out in the
installer- providing the hint that This option has been disabled because JRun4
has been detected on this system. Uninstall JRun4 and then install CF7 in
multiserver mode."

I then uninstalled JRun4 and ran again, receiving the same prompt. I looked
through the registry and didn't find anything I could eliminate to remove the
conditions which make the installer think that JRun is still installed.

Make sure the c:\jrun4 folder is not present (if it is, and you want to keep it, just rename it). Then run the install again.
