I am unable to access user guide it gives an error - launch pdfdoc error ...... etc please refer to HP development
Before going on, I would like to check whether the issue that an user guide unable to access? If so, what kind of file is this?
Meanwhile, please try to check the permission:
1. Right-click the file or folder, and then click Properties.
2. Click the Security tab.
3. Click a user name or group under Group or user names.
The permissions for the selected user or group are shown in the lower portion of the properties dialog box.
If you can try to get the full control to test the issue.
If the issue persists, try to
Take Ownership of a File or Folder.
What are permissions?
Hope this helps.
