Downloads / Updates for Registered Users

Current version: 8.4.1

Registered users of our products can download the present full versions of OptiVec and CMATH from this page. The ZIP files and the INSTALL.EXE files contained in them are password-protected. Our registered users get the passwords by e-mail. If you are a registered user and did not receive the password, please drop us a note at optivec%at%gmx.de (replace %at% by the @ sign)! Consult the documentation of your unzip program about how to uncompress password-protected files. In most cases, you will be automatically asked for the password through a popup dialogue.

You should install the files from this page over any previous version (trial or full) of OptiVec or CMATH; in other words, you need not deinstall your previous version, but simply overwrite it.

If you install the Registered Version over the Demo Version, be sure to recompile your project(s). (Remember that applications, containing functions of the Demo version, cease functioning after 90 days and shall not run at all on your clients' computers!)
