What is the catch? The trial edition software is free, but after 30 days, it will stop working. At that point, I hope you see how much of a bargain RockSim really is, and will consider investing in a full copy.

Installing the Software

Macintosh Computers:

Here is a QuickTime Video that will walk you through the installation of the software if you are not computer savvy. Click Here to View.

Take the RockSim 9 folder, and drag it out of the .dmg drive and PUT IT IN YOUR APPLICATIONS FOLDER.

Open the folder and launch RockSim 9. You will be asked to install some PACE extensions. You MUST do this.

Known Macintosh bug: If your mouse freezes up with RockSim, just hit the TAB key on your keyboard. That will refocus the mouse on the computer screen.

Window's Computers:

RockSim 9 will install in a NEW directory during installation. If you have version 8, you do not need to delete it. The download you just completed is a FULL installation, and doesn't even need the old version 8.


Actual Customer Comment:

"RockSim is a huge hit around our club. I got back into model rocketry a year ago, and I must say that AP motors, altimeters and RockSim are three biggest developments since I launched rockets as a kid back in the 70's. I'm not just kissing your butt. Designing and building would take four times as long and double the cost if I didn't have RockSim... Not to mention, some complex projects would simply be impossible." -- Mike Ritter


Actual Customer Comment:
"I read some only some of your website, but do recall you mentioning that you 'get' your fellow rocketry customers. From the information your site provides (and I only scratched the surfaces of the articles you list) I would say that you do 'get' it. I look forward to the prospect of supporting a business that openly shares so much knowledge with the community."  -- Doug Willard
