I’m trying to set up an Apache Tomcat 7.0 server in Eclipse, but I can’t get the wizard to let me create it. My NEXT button won’t highlight after I select Tomcat v7.0 like so:

I don’t have the same problem trying to create any other version of Tomcat, just v7.0:

Info about my system:
-I’ve had it up and running previously, but had to go through a reboot with my system, Eclipse was untouched as it was on a different HDD
-I’ve reinstalled Tomcat 7.0 twice, once to the drive containing this particular Eclipse Workspace, and once to my main OS drive, both to no avail.
Can anyone tell me what I did wrong here or what’s going on here?
Thank you very much.
In your eclipse menu go to
window > server > runtime environments > hit add > select tomcat 7 > hit next
press browse and navigate to the installation directory
and finish. Will solve this issue.
