The MSI version of the OAK installer is a 17Mb file which contains the program files together packaged in a form acceptable to the Microsoft Software Installer built into Microsoft Windows. Download and run this file, and it will install the software on your hard drive.
Consult the support page if OAK does not download or install easily.
The download is a fully functioning version of the software. It will function for 30 days from first use. After this period has expired, you must purchase a license and register to continue the use of the software.
Use of OAK is subject to the standard license conditions and you are required to agree to this before downloading your copy of the software. Downloading, installation, or use, of OAK is your acceptance of this License Agreement and Warranty.
I have read the License Agreement and accepted its terms and conditions and I would now like to download a copy of the Operis Analysis Kit for evaluation.
If you have any questions at all, please do not hesitate to contact OAK support.
