Black Ice Software suggests contacting Technical Support via impactsupport@blackice.com for technical guidance before uninstalling and reinstalling the TIFF Viewer.
If Tiff Viewer is uninstalled within the demo period, a demo registration number is provided. Make sure to save this number in case the Tiff Viewer is reinstalled within the demo period.
During the next installation when Tiff Viewer tries to register itself, the following screen appears and the saved Demo Registration Number is required to re-register. Paste the code to the Your demo license number field.
