SYMPTOMS

When you start Microsoft Reader on a desktop or a laptop computer, you may receive the following error message:
Unhandled exception 0xC0000005: AV

CAUSE

This behavior can occur if both of the following conditions are true:
  • Less than 300 megabytes (MB) of space is available on your system hard disk (the hard disk on which Microsoft Windows is installed).
  • Less than 300 MB of space is available on the hard disk on which the Microsoft Reader software is installed.

RESOLUTION

To resolve this issue, increase the amount of available hard disk space on your system hard disk and the hard disk on which the Microsoft Reader software is installed.

To do this, use the following methods in the order in which they are presented.

Install the Microsoft Reader Software on the System Hard Disk

If the Microsoft Reader software is installed on a hard disk other than the hard disk on which Windows is installed, uninstall the Reader software and then reinstall the Reader software on the system hard disk.

NOTE: The default installation folder for the Reader software is
C:\Program Files\Microsoft Reader
which is the system folder on most computers.

Install the Reader Software on a Different Hard Disk

If more than one hard disk or hard disk partition is installed in your computer, install the Reader software on a hard disk that contains at least 300 MB of available space.

For information about how to determine the amount of available space on each of your hard disks, please see the "More Information" section of this article.
