 You can follow most of these steps if VPOP3 was on a PC that died, and you are moving it to a replacement PC. However, this is less ideal than [[restore_a_backup_of_vpop3|restoring from the latest daily backup]] you made. If you were not previously backing up VPOP3, this may be a [[http://​www.pscs.co.uk/​products/​bfw/​index.php|good time to start]]... You can follow most of these steps if VPOP3 was on a PC that died, and you are moving it to a replacement PC.

If you do not enter it, make sure you choose the correct edition of VPOP3 VPOP3 Basic or VPOP3 Enterprise 
 +  * During the component selection stage of the installation,​ make sure you **check** the '​Database Server for VPOP3' option. Sometimes this will not be checked by default during a move operation

 +====Moving installation directory====
 +If you are installing VPOP3 in a different directory on the new PC than it was on the old PC, you need to change some settings.
 +
 +This needs a little utility. You can download it from http://​www.pscs.co.uk/​downloads/​vpop3settings.zip . Download this file, and extract the contents into the new VPOP3 installation directory
 +
 +At a command prompt, find the VPOP3 installation directory and run
 +  vpop3settings replacepaths <old path> <new path>
 +  ​
 +e.g. Run
 +  vpop3settings replacepaths c:\vpop3 d:\vpop3
 +  ​
 +The utility will display all the settings which used the old location and ask if you want to change them to the new location. Check the settings, and press '​Y'​ if they are correct

 +=====Disable VPOP3 on the old PC=====
 +If the old PC will still be being used for other things, and you do not want VPOP3 to run on it, you should disable VPOP3 on it.
 +
 +If you don't do this, you may end up with two copies of VPOP3 running at the same time, which will almost certainly cause strange things to happen.
 +
 +There are two main options here:
 +  - Disable the VPOP3 service
 +  - Uninstall VPOP3
 +
 +====Disable the VPOP3 service====
 +Go to **Control Panel -> Administrative Tools -> Services** on the //OLD// computer
 +
 +Find the **VPOP3** service. Double-click it. If the Service Status is '​Started',​ press the**Stop** button. In the **Startup type**, choose **Disabled** and press **OK**
 +
 +Find the **VPOP3DB** service and do the same again
 +
 +====Uninstall VPOP3====
 +Only uninstall VPOP3 if you will not want to run VPOP3 on this computer again, as it will clear all the data.
 +
 +Go to **Control Panel -> Programs and Features** on the //OLD// computer
 +
 +Find the '​VPOP3'​ program and uninstall that.
