I got the link to download and Install Passollo 2011, 2015, and 2016. When trying to open them I get the following error:
If Passollo is free, where do I get the license?
The full Passolo version is not free. You need to buy a license. But there is a free Translator Edition that you can download here: https://www.rws.com/localization/products/passolo/translator-edition/ The Translator can be used, if you received bundle files (TBULICxx) from translator vendors or software manufacturer to be translated.
