When I try to open a downloaded PDF file it opens for about 6 seconds and then closes - how can I fix that?

I am using a Dell XPS8500 desktop with 64 bit Windows 7. No problem downloading PDF files but when I open them they disappear before I can print.

Hello,

Which application are you trying to open the PDF files in? Firefox or Adobe Reader? Or another?

If adobe reader then please make sure that your copy is up to date. You can get the latest version here - http://get.adobe.com/uk/reader/

Also I notice that you are using Firefox 19. Unless you have a particular reason to run an old version of Firefox is it much better to keep updated. The latest version is v22. New security fixes are applied in every new version of Firefox. Without them your PC is vulnerable. Please see this article: Update Firefox to the latest release

I had this problem too, though I don't even get 6 seconds in the PDF file. this just started after I downloaded v23. I went into TOOLS/OPTIONS/APPLICATIONS and clicked on Portable Document Files (PDF). Adobe was my default and I changed it to Adobe in Firefox. The problem was resolved.
