The COM2TCP software is free to download and distribute. However, there is a 45 day trial period which begins when the application is run for the first time. A license key must be purchased to re-enable COM2TCP after the trial expires.

The license covers the current release and a new key may be required to activate features for future major releases (if significant features have been added).

We also recognize that astronomy is a hobby that is ruled by weather and seasons and that it may not be possible to get sufficient use from COM2TCP over the trial period. If this is the case, then feel free to contact us at: and we will be happy to extend the trial period for you.
