PaperOffice will now run a diagnostic and determine if perhaps the virus scanner is blocking any components.

PaperOffice will collect diagnostic data in the background and provide it to the technical support after your confirmation, only system data will be collected. Confirm the next message with OK.

Log in now and perform the steps that will cause the failure. After the error has occurred, stop PaperOffice immediately by clicking on "X" in the upper right corner. PaperOffice will now restart automatically and diagnostic data is ready to be sent.
Describe the problem step by step now. Do not include personal information, such as your email address. Write down your diagnosis ID to inform the technical support team. Then click on "Send diagnostic data now and continue".
