After installing Windows 7, I mistakenly ticked Picasa to open pdfs. ("Always open with...) Of course it doesn't. Now every time I double-click a pdf to open it, Picasa tries but comes up with the message "Invalid File". What do I need to do to prevent Picasa from thinking it's the default program for opening pdfs?

Hi Rufous,
You should be able to open a file explorer window, right click on a PDF, choose Open With and then select the Choose a Default Program. Choose your PDF viewer program and make sure to check the box "Always use the selected program to open this kind of file."
Hope this helps,
