PDFCreator by PDFForge has made changes to the way the new patches for PDFCreator free edition are handled silently.
As of version 3.2.1, it is noted that “From now on silent installation is only available for PDFCreator Business, PDFCreator Terminal Server and PDFCreator Custom”. In our testing of version 3.2.1 and version 3.2.2, we have confirmed that although the silent switch in the deployment logic will still work for some machines, we found that no machines joined to a domain, will work silently at all.
When adding a silent switch to the installation commands, we have found that the installer will not even run.
Because of this change, support for versions newer than 3.2.0 will not be supported until they are able to be run silently.
