Install Trillian 5 in the same directory as your previous version of Trillian.
If you are feeling cautious about upgrading an existing installation, you can make a copy of both your C:\Program Files\Trillian folder and your user data folder. Windows Vista and 7 users can find their user data folder in C:\Users\username\AppData\Roaming\Trillian, while earlier operating systems place it in C:\Documents and Settings\username\AppData\Roaming\Trillian. If Windows Explorer doesn't let you see those folders it is because they are hidden. You can configure Windows Explorer to "Show hidden files, folders" by changing the setting in the "View" tab of Folder Options.
