the pdf works well for me in acrobat reader x pro. But in acrobat reader x, it gives permission error, despite disabling protected mode.
We are sorry for the trouble. As dscribed Acrobat Reader X is giving permission error
Is this a behavior with a particular PDF file or with all the PDFs? Please try with a diffrent PDF file and check.
What is the version of the Adobe AcrobatReader X you are using? To check the version go to Help > About Adobe Acrobat Reader
