As of January 2016 we are unfortunately no longer able to provide technical support for old installations of Grammatica for Windows.
Grammatica for Windows was first published in 2011 and runs on Windows XP, Vista, 7 and 8. As we are shifting our focus the the online version of Grammatica, we have not offered new installations for more than one year.
We do, however, still provide existing customers with the possibility of downloading Grammatica for Windows, as well as to reset their license in order to be able to transfer Grammatica to a new computer, or upgrade the operating system on an existing computer.
You can download Grammatica for Windows here, and you can reset your license by filling in your e-mail address below.
