I have get bored saying years now, don't install Elxis inside a folder...I know that it should work there and if the installer has a bug I will fix it but please don't destroy elxis by putting it inside sub-folders. Especially when there are other sites above it with htaccess overlaps, it becomes a mess...Elxis is a CMS, it wants to be the master of the web site, not a sub-script.
I have 3 elxis 2009.x working at the moment that way for demo purposes to show different extension usage.I have contacted wamp to find out about the missing dll file.
