Built-in viewer consists of a software component
called ActiveX.
The ActiveX is usually installed when Built-in viewer
is used for the first time. However, installation may
be rejected depending on the Anti-virus software
settings. In this case, change the settings of the
Anti-virus software before installing Built-in viewer.
