Quick Calculator 2.5, Non-demo Flash Calculator, and DMSolver ask you to register with me at the start of your free 30-day use period and again later if you decide to purchase a license. These are serious software packages embodying years of development and are copy-protected. Because they are copy-protected to the point that a hacker would have to exert much effort to bypass the protection, you can be quite well assured that you are getting a true copy from me. You send me by email a set of codes from the installer, and I send you unlocking codes back.
There is no typical online sales mechanism in this simple website. To make a purchase let me know by email. You will get a PayPal invoice which you can pay by credit card (including using non-USA currency). Then you run SETUP.exe again for a new set of codes and I send you new codes back.
None of our software puts any hidden system files or registry entries into your system, so if you delete all the files, it is uninstalled.
Likewise BOAT3D is a serious effort by 2+ people over many years. For it we offer subscriptions over fixed periods. During the subscription period the user is entitled to current upgrades and a reasonable level of support. Contact us by email or other means to request a subscription. 30-day short-term trial subscription .......$300. To subscribe to use BOAT3D for longer periods, please email me for current policies.
The following are self-extracting .exe files. When you run them they first ask you to specify a new folder into which the software is installed (specify an existing folder if you want to upgrade).
In every case you will get a warning from Windows about an "Unknown Publisher"! This is because I have never taken the time and expense to have an official Microsoft encrypted "certificate". Also note that I have encountered some computers that have very secure malware stoppers which will not let any of these .exe files in. In this case you may have to email me, and we might be able to figure something out. For every .exe file there is a corresponding .zip file, but some malware stoppers don't like .zip files containing .exe files either.
