# Error -560 invalid private/public key

Resources

This error often happens if you attempt to access a client that has a problem with the public key file or with the password assigned during install.

## Problem with one client

If this is occurring on some of the clients and working for others, it may be a corruption in the specific clients "pubkey.dat" files.

To fix the problem do the following:

Go to the client computer

Run the uninstall script included with the Retrospect Client installer

Go to Library/preferences and delete the retroclient.state file

Copy the public key (pubkey.dat) from the server found in "/Library/Application Support/Retrospect/pubkey.dat" and include it in the "pubkey" in the client installer.

Reinstall the Retrospect Client. Retrospect should prompt you to enter a new password during the install process.

Go to the backup server and re-add the Retrospect Client.

Go to the client computer

Go to Add/Remove programs and uninstall the Retrospect Client

Copy the public key (pubkey.dat) from the server found in "C:\Documents and Settings\All Users\Application Data\Retrospect" and paste it on the client in the "C:\Program Files\Retrospect\Retrospect Client" folder.

Re-install the Retrospect Client

Go to the backup server and re-add the Retrospect Client.

## Problem with all clients

If this appears to be occurring on all of your clients, recreate the public/private key and redistribute the updated client. Be sure to uninstall the client prior to reinstalling the client with the new public key.
