Hi to all,

I am reviewing some notes from my previous training, so I decided to open those PDF files that was given to us by the trainer, when I am about to open the file, an error message appeared, access denied to the file, I include in my post the error message screen shot.

Adobe Reader

There was an error opening this document. Access denied.

As I looked upon the error message, I have a hard time understanding the error, on why I cannot open the file, since I am the owner of the file, I don't remember adding some restriction on the file, I scan my computer for some virus that might locked the file, but none was found,

Please help me find ways to open the file,

Many thanks to all.

The file might be encrypted, try to do the following. Right click on the file and then click Properties, click the General tab and then click the Advanced button.

There might be some problem with the access right for that file. It might happen when you have not got administrative permission to open the file.
Go to Start menu >> All Programs. Right-click on the “Adobe Reader” shortcut and click on “Run as administrator”. When promoted, click “Yes”.
Then drag and drop the PDF file.
Also, there are another way you can use.
