Perhaps this is related: I noticed just recently after my IT folks installed a new desktop PC for me, that anytime I click on the pdf files for documentation with R packages that I get an Adobe error message about can't open the file because it doesn't strart with '%PDF%' . But if I download the file to my hard disk and then click on it Adobe has no problem opening it. I'm using Adobe Reader 7.0 and Adobe Acrobat Standard 7.0.

This message is one which Acrobat Reader puts out when asked to read a "damaged file" and is an unlikely response from a browser trying to access a "broken link".

Either there is a problem with your Acrobat Reader or its installation as a "helper" in Explorer, or there is indeed something wrong with the files you tried to download.

The latter is (I hope) very unlikely! (given that you "randomly chose various packages").

If you specify one or two packages for which you got this error message, some of us can try for ourselves, cross-check your experience, and report back. This should help to localise the source of the problem.
