I am on Windows 10. I uninstalled the old PDFCreator program, and it no longer appears in the installed program list. I then tried to install the new version (2.3.2) and get this error:
PDFCreator is already installed, it is necessary to uninstall the existing installation (version 0.0.0) before installing PDFCreator 2.3.2.
Version 0.0.0? Where is that coming from? When I click Yes to continue the installer, I get this message:
Runtime Error (at 309:207): Internal error: An attempt was made to expand the "app" constant before it was initialized.
I have found others with similar problems trying to install, and the advice was either to uninstall the prior version (which I did, but remnants still remain in the registry it seems), or to try a Forced install. So, I setup a shortcut to run the installer in Forced mode: PDFCreator-2_3_2-Setup.exe /ForceInstall
This too gives the same errors as above. I then downloaded and ran the Revo Pro Uninstaller program, but couldn’t get it to find the old version to clean up. I’m guessing there is a registry entry somewhere that needs deleting, but what is it?
