I have some PDF files stored in our Workgroup PDM Vault, which are not solidworks drawings, just documents.
Through Solidworks Explorer, I used to be able to select the PDF file from the folder tree, and a preview would appear in the bottom right side of the screen. From here I could scroll through the document, save it elsewhere or print (without needing to check out, brilliant)
Now the preview does not work. When I select the document, it says 'you must download Adobe reader to preview PDF files' with a link to the website.
I already had adobe, but I did it anyway and am on Adobe 10.1.
The problem started when I installed Adobe Writer trial, which I had to uninstall and go back to using Adobe Reader.
