|My suggestion in #1 should have sorted this out - like this:|
Right click any saved pdf file, select "Open with" and see if Adobe Reader appears on the list. If so select that.
If it isn't listed then use "Choose Program" > "Browse" and follow this path:
Program Files > Adobe > Reader 9.0 > Reader > AcroRd32.exe
AcroRd32.exe is the file you want.
Ensure you check the box that says:
"Always use the selected program to open this kind of file".
Always pop back and let us know the outcome - thanks
