"This Win2PDF license has been activated too many times and has been blocked (error 13903)."


The Win2PDF activation process allows for Win2PDF to be reinstalled and PCs to be upgraded, but there is a limit to how many times the license can be activated. If the number of activations exceeds this limit, this error will occur.


To purchase additional licenses of Win2PDF, see the Win2PDF purchase page. Volume license discounts are available.


If you only have Win2PDF installed on single PC and believe this is an error, please contact support support and provide your license code.
