Context menu problem

If I'd like to "merge", or "convert pdf files" from Windows context menu, but I get this message:

"Couldn"t find PDFCreator in your system. Please check if you have installed it."

I've uninstalled and reinstalled the PDFCreator, but the problem not repaired.

Version: PDFCreator 4.0.1
Windows 7, 64 bit

Could you please reinstall PDFCreator by following this guide and using the PDFCreator 4.0.1 "legacy setup"?

I followed the guide, make uninstall and reinstall, but the problem still for me.

In the meantime, I figured out what was causing the problem.
The PDFCreator context menu works well in Windows File Explorer (I use hungarian Windows, in context menu the Merge item text = "Egyesítés"). When I use the context menu in Windows File Explorer the task is accomplished.
But in Total Commander, in context menu the visible text is "Merge", and I get this message:
"Couldn"t find PDFCreator in your system. Please check if you have installed it."
Could this be fixed, or is it the fault of Total Commander?

i can't remove pdfcreator from the contextmenu.

plzhelp

interesting. as far as i have tested, this bug appears only on rtf-files. i have reinstalled and deleted pdfcreator again and again.
