Tiff Viewer is licensed per PC. One license is good for a single PC with unlimited users. Currently TIFF Viewer offers two types of licenses:
- Static license
- Transferable license
What is the difference between the transferable license, and regular (static) licenses?
The regular (static) TIFF Viewer license is tied to a computer, therefore even if one bought a new computer, TIFF Viewer cannot be reinstalled and registered on this new computer, since the license is already used up.
On the other hand the transferable license validates the license periodically, and it is not tied to a computer, therefore if you would like to move your already registered TIFF Viewer to a new computer, you can do it very easily by following the steps described in the Moving transferable license to another computer section. For more information about the transferable licenses, please refer to the Registering the Tiff Viewer with transferable license section.
Please be informed, that TIFF Viewer tries to validate the transferable license periodically over the internet, therefore we strongly recommend having active internet connection at least once in a month!
Registering TIFF Viewer with transferable license
In order to purchase the license, click Purchase when TIFF Viewer start and the Online Store will be launched, where any number of required licenses can be purchased.
A Tiff Viewer serial number is provided after purchasing. To register Tiff Viewer during the demo period or to resume full functionality from the free version once the demo has expired, click Register (administrator privileges required). The following dialog appears:
Enter the serial number in the text field and press OK. The serial number is in the body of the email containing download instructions for Tiff Viewer and Browser Plug-In.
NOTE: An active internet connection is required in order to license the software. The serial number contains dashes that are part of the number.
The software will register over the Internet connection via Port 443 (HTTPS) to query the Black Ice license server and verify that a valid serial number was entered.

Online License Validation
Transferable license requires online validation once in every month. If TIFF Viewer is registered with a transferable license, then the TIFF Viewer attempts to connect to the Black Ice License server via the internet, and validate the license. For the validation, the TIFF Viewer requires active internet connection on the computer, for at least once in every month.
In order to make sure that your license is validated, please enable the internet connection on the computer, and restart the TIFF Viewer to initiate the license validation at least once in every month. The validation is an automated process; TIFF Viewer will only notify the user about occurring errors.
In order if your computer is not connected to the internet for more than a week, TIFF Viewer will notify you from the days left to validate the license.
Click on the OK button to continue using the TIFF Viewer. TIFF Viewer remains fully functional and can be used until 30 days without online validation.
If the time period for the online validation is expired, and TIFF Viewer was unable to validate the license due to the lack of active internet connection, TIFF Viewer offers the following options:
- One can attempt online validation by clicking on the Retry validation button. Before retrying the online validation, please make sure that your computer has active internet connection.
- Register with different serial allows the Administrator to register the TIFF Viewer without active internet connection, due to manual registration. Please be aware, that after the manual registration, the license will not be transferable anymore! This option is recommended in highly restricted environments without internet connection.
- Continue in Free mode allows users to run the TIFF Viewer with limited functionality.
