Hey there,
I've been working on this for hours... I cannot reinstall PDFcreator because it cannot install printers. So I get the message about repairing and then the error that it cannot be repaired contact your administrator or support. I've been running everything as an admin.
Things I've tried:
PrinterHelper.exe /InstallPrinter PDFCreator /PortApplication “C:\Program Files\PDFCreator\PDFCreator.exe”
Deleting the registry key with Pdfmon
I've uninstalled and reinstalled multiple times.
Restarted multiple times.
Scoured the registry for everything related to PDFCreator and PDFForge and deleted it all.
Given permissions to C:\windows\system32\spool\drivers\x64\PSCRIPT5.dll and removed it.
Probably many more things (just google "Can't Install PDFCreator" and I've tried everything ever suggested).
