To get started with OAK, download it from this web page and install it on your computer. It will function for 30 days from installation. It’s the full thing, not restricted in any way.
Even if you have already evaluated OAK 4.0, 4.1 or 4.2, the current version 4.3 will provide another 30 day evaluation period.
If you already have a license for OAK 4.0, 4.1 or 4.2, you do not need to buy a new one to use this version. However, OAK 4.3 uses a different licensing system, which in the presence of adequate internet connectivity, completely automates the purchasing and activation of licenses.
If you upgrade an existing licensed installation, your old license will continue to work, and you will have the facility to exchange your old license key for a serial number.
If you perform a clean installation, you will need to contact Operis’s London office to get a new serial number.
OAK is packaged as a single .msi file.
