Sorry about that. I'll add support for alternate admincp directory names in RC2. I'll probably put it out tonight - that's two significant issues with the installer.

Other than that thing though, has anyone had problems with items other than the installer?

I will change this with RC2 - it is a significant issue. I'm sorry I overlooked it and appreciate your patience with this matter.

They need to be writable at the time Joomla is installing or uninstalling modules and components. You can chmod them to be unwriteable most other times - though be aware that vJoomlaRecentThreads and vJoomlaWho'sOnline won't be able to cache results if you do (they will not publically error when this occurs though).

For best security you can make the directories unwritable except when you are installing or uninstalling modules, mambots and components in the vJoomla admininstrator.

If you have a Linux or Unix server you have the alternative of creating a symbolic link to those directories. If you do this you must include an .htaccess file with the Allow Symlinks directive turned on AND the server needs to be setup to parse that .htaccess file (most are). The creation of symbolic links is a fairly technical process.

Either location is fine by me, I check both regularly.

I have tried EVERYTHING and cannot get input the right "forum path" for the installer to locate it. Any ideas?

I have it set up to a subdomain, http://forums.pinkowitz.org, and told it to go there. For the subdomain I inputted:

http://forums.pinkowitz.org
forums.pinkowitz.org
forums.pinkowitz.org/includes/config.php

None of those worked. I then tried copying the vBulletin folder into my vJoomla subdirectory, accessible at http://pinkowitz.org/vBulletin. I then tried to no amise:

http://pinkowitz.org/vBulletin
pinkowitz.org/vBulletin
pinkowitz.org/includes/config.php

I'm stumped. Any and all help would be appreciated :)

You seem to be confusing internal and external paths. On a linux machine the complete internal path will start with a /. On Windows it will start with a drive letter, such as c:\

You must provide the internal path from the root of the drive to get the script to work. For example

/var/www/sites/pinkowitz.org/subdomains/www/ for Joomla and
/var/www/sites/pinkowitz.org/subdomains/forum/ for vbulletin, and so on.

One way to discover the path is to create a new php file in your forum with this code
Visit the file in your browser and copy whatever appears to the vJoomla installer.

Can someone plz post screen shots of the admin interface? Is this a CMS?

/homepages/13/xxx/htdocs/xxx

is what returns when I make the php file and access it. The installation proceeds but then results to a white login screen, which differs from the normal blue login screen. When I continue to log in, I get a 500 Server Error.

Any clue as to why?

EDIT: I'm going to try to put it in the same directory as vJoomla. Hopefully that'll work.
EDIT 2: Nope. Still getting the white screen. A funny thing I noticed though is when I scroll over "Pinkowitz.org Forums" on the white login screen, its location is pinkowitz.org/index.php when it should be forums.pinkowitz.org/index.php. Any ideas as to why this is?

You MUST log into you admincp before starting the Installer or it will not work beyond step one.

http://demo.joomla.org/demo10/

They have a demo of the interface there. vJoomla isn't markedly different than Joomla in this regard.

I am logged into admincp in a different window. Am I doing something incorrectly?

Hmm... Your login might have timed out. Try reloading the page and seeing if you are prompted to log in. If that isn't the problem then the cookie domain setting is probably the monkey in the works, and I'm not sure that's solvable.
