I used to recommend to my clients to use PDFCreator as a free program that would allow printing to PDF files instead of having to pay for Acrobat.
Lately they've started auto updating and including PDFArchitect which is an alternate editor, but does not work for many of my clients' workflows or compatibility with their other programs. But it automatically becomes the default program upon installation.
When opening PDFs in IE, they open in a pop up window within IE using the PDFArchitect plugin.
Regardless of anything I have tried, uninstalling the program, uninstalling or disabling just the plugin, searching for remaining files or registry keys and deleting those... PDFs now attempt to open in the pop up window, but since the program is missing it is just blank. I have tried repairing Adobe Reader and Acrobat, changing their view settings, and I still have issues.
I have Googled around and can't find any other sites addressing this issue, and really need to get my clients working again without having to reimage their computers...
Has anyone here seen or fought this issue before? Any ideas?
