What if you still have questions? You can use Discussions to ask for additional help.
However, in order for someone to help you, you need to provide the following information:
  • Sumatra PDF version you’re using
  • your OS (Windows) version
  • did you download an installer or zipped executable?
  • where did you download the Sumatra from (the url of the webpage you used to download Sumatra)?
  • is there SumatraPDF directory in your program files directory (usually “c:\Program Files” or “c:\Program Files (x86)” on 64-bit systems)?
  • what evidence there is that Sumatra is installed? Be precise and specific. Don’t just say “there’s a link to it”, tell us where that link is, what is the name of the link etc.
To emphasize: if you don’t provide this information, we cannot help you.
