Install & Upgrade
PDF Annotator Setup is asking for a username and password, which I do not know.
If you get asked for a username and a password (or email address and password) when trying to install PDF Annotator, this question comes from your operating system (Windows), not from PDF Annotator.
To install PDF Annotator, you need to have Administrator rights on your computer.
If you do not have Administrator rights, your operating system (Windows) will ask for a username (or email address) and a password. This process is called "Windows User Account Control" (UAC).
To continue with the installation, you will need to enter your local Administrator username and password. If you do not know this password, contact your computer administrator to enter the information.
