ThinkUp doesn’t run on your desktop computer like a regular application. You’ll need a web server to install and run it. Typically users purchase a web hosting plan and install ThinkUp on it the same way they’d install WordPress.
Here’s how to install ThinkUp.
If you don’t have access to a web server, you can run ThinkUp for free on PHPFog or try our ThinkUp Launcher for Amazon EC2. Alternately, power ThinkUp users have documented how to install ThinkUp on Windows and Mac OS X on the community wiki.
