Hello et. Thank oyu for trying TeamTrick.
I never tried to run TeamTrick with Ruby 1.9 so I can't say for sure
if it will work or not. I recommend you to use Ruby 1.8.
Regarding the "msvcrt-ruby18.dll was not found" error, it might be
caused by the native SQLite implementation that is shipped with the
zip file in the download section. It must be asking for Ruby 1.8
libraries. If you feel comfortable with the command line, you can try
cloning the GitHub repository and setting up the installation
yourself. See the "Installing from source section" here
https://github.com/manuelmorales/teamtrick.
Hope this helps : )
