(Also applies to version 1.x)

To move VPOP3 to a new PC you should go through the following steps:

1. Copy the VPOP3 directory and subdirectories from the old PC to the new PC
2. Run RegEdit on the old PC and export the registry branch: HKEY_LOCAL_MACHINE\SOFTWARE\PaulSmith\VPOP3
3. Run RegEdit on the new PC and import this registry branch
4. Reinstall VPOP3 on the new PC into same directory where you coped the VPOP3 directory in step 1
5. If you are using any VPOP3 addins (eg avast! for VPOP3, the VPOP3 FaxServer etc), you should reinstall those on the new PC as well

If the new PC's IP address is different from the old PC's address, you may also have to go around the client computers changing the email client settings to point to the new mail server. You may also need to check the IP Address to Bind to setting on the Services → General page, and the Access Restrictions on the various Services → xxxx pages.

If you are changing the directory where VPOP3 is installed (eg from c:\program files\vpop3 to d:\program files\vpop3) then you may also need to change directory settings in VPOP3:

• Check the Utilities → VPOP3 Extensions settings page for any file paths which need changing
• Check the Services → WebMail/Admin settings page, and check the Mail HTML Pages setting is correct

This procedure will work between any two 32 bit versions of Windows, see below for modified instructions for 64 bit versions of Windows

If you are upgrading the version of VPOP3, eg 1.3.0 to 2.3.0, or VPOP3 Standard to VPOP3 Enterprise, simply install the version you want to use (the version you are upgrading to) at step (4) in the sequence above.

64 bit Windows stores registry entries for Windows programs in HKEY_LOCAL_MACHINE\Software\WOW6432Node instead of in HKEY_LOCAL_MACHINE\Software, so, after step 2 above, run NotePad and load in the .REG file which you created in step 2. Then, go to Edit → Replace. In the Find box, type HKEY_LOCAL_MACHINE\Software\PaulSmith\VPOP3, and in the Replace with box, type HKEY_LOCAL_MACHINE\Software\WOW6432Node\PaulSmith\VPOP3, and press Replace All

Then continue with step 3 above

64 bit Windows stores registry entries for Windows programs in HKEY_LOCAL_MACHINE\Software\WOW6432Node instead of in HKEY_LOCAL_MACHINE\Software, so, in step 2 above export the registry branch HKEY_LOCAL_MACHINE\Software\WOW6432Node\PaulSmith\VPOP3 instead of the registry branch given above. Then, continue with the rest of the steps as above.
