Use Microsoft office and then convert it to a PDF file, that is what the printers have been telling me.....

I too had such a problem. I tried to delete a folder containing just pdf files, but wasn't able to delete even after exiting adobe reader. My case was, I was running google desktop (indexing software) running in background, which was accessing that folder, so as to not allow me to delele it. If you have such softwares running in background, it may be a reason for your case. Try exiting it and then delete the folder. Whatever be the case restarting the system must solve the problem.

Sometimes due to no fault of your own, upgrades and downloads just don't work.  I had a similar problem a few months ago with Adobe.  I went to my add/remove progams in the contol panel and deleted the Adobe Reader.  I went back to their web site and downloaded the latest and greatest.  No problems at all. Just make sure you uncheck the toolbar option and the photoshop starter edition (unless you really, REALLY want them.)\n\nhttp://www.adobe.com/products/acrobat/readstep2.html\n\nplrr

Adobe Reader can only read pdf files, Acrobat is a pdf editor, you can make your own pdf files

Try this\n\nusing System.Diagnostics;\n\n\nstring Path_of_PDFFile;\nPath_of_PDFFile = <PATH>; //Remember to use // instead of / when setting path.\n\nProcess.Start(Path_of_PDFFile);

You would have to see if the program you are using to make the PDF File supports password on it or not. Check the help on it. If not then your best option would be to put the PDF file in an Archive ( zip or rar ) Winzip and RAR allow you to put password on your files. So any one who would want to extract the pdf file would have to enter the password before reading it.

I'm going to assume you have installed the drivers for your card reader.  When you plug any kind of storage device into your computer.  You should automatically get a window that pops up that asked you how you wish to open the files.  If this window does not open up, your auto it program has ceased to function.  Below is a link to a program that can fix this for you.

If you want a free utility, do a search for "Cute PDF".  It's simple, free and easy to use.  Highly recommended.  Just don't tell Adobe!!!!

Did you have MS Office as a trial version? The trial period may have expired.\n\nYou can open those files using WordPad, Notepad or Openoffice. I would recommend OpenOffice, as I am a big follower of Free Open source applications.

you might have to uninstall your previous adobe reader or it could be a website malfunction

Re-Download it as the correct file type?\nTry changing the files properties with regard to what it opens with?\n\nThats all I can come up with! =(
