Hello, I am currently trying to do the same. It's a complete fresh install.
What OS and version are you using ? Are you using the rt4 packages provided by the distribution or are you installing from source ? This is what I tried so far: I installed the debian rt4 packages on Debian stable 6.x squeeze. Unfortunately squeeze does not provide rt4 and assettracker packages so I use the packages that are available in debian testing (using apt pinning). After some tweaks (there were issues with the mysql schema about TYPE=InnoDB which now must be ENGINE=InnoDB) I managed to install asset tracker but I got display errors in the rt start page. Next I tried the same using Debian testing instead of stable. But got the same display issues. Next I tried debian testing and installing from source wget http://download.bestpractical.com/pub//rt/release/rt-4.0.6.tar.gz git clone https://github.com/chakatodd/rt-extension-assettracker basically installation went fine, but again I am getting display problems with the rt start page. What I see in the front page is the text: <LABEL ACCESSKEY="9"> <SELECT NAME ="Type" onchange="document.CreateAssetOfType.submit()" class="select-assettype"> </SELECT> </LABEL> and Here is a Screenshot: http://files.muellers.ms/rt4-assettracker.png I guess this is an CSS issue or rt-extension-assettracker is not (yet) compatible to rt4 ? Thanks Carlos
