Can I use IPXCControlEx to return the current version of the PDF-XChange Driver installed on the local computer?
Please note that a developer asked this question in the PDF XChange forum. Their software contained a feature that only worked with specific versions of our software. They wanted to be able to return the current version of the software to their users and warn them, if necessary, about compatibility issues and advise an update.
Yes, file versions are available for some items, for example pdfSaver4.exe and drvui40.DLL. The "InstallPath" key in the registry points to the folder that contains these items:
HKEY_CURRENT_USER\Software\Tracker Software\PDF-XChange 4.0\Drivers
or
HKEY_LOCAL_MACHINE\Software\Tracker Software\PDF-XChange 4.0\Drivers
