(Also applies to version 1.x)

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

Copy the VPOP3 directory and subdirectories from the old PC to the new PC

• On the original VPOP3 computer, run REGEDIT.
• Find HKEY_LOCAL_MACHINE\Software\PaulSmith on the left.
• Right-click the VPOP3 key on the left, and choose Export.
• Save it to a .REG file, eg VPOP3.REG
• Copy the file to the new PC
• Double-click the .REG file to import it into the registry on the new PC

• Reinstall VPOP3 on the new PC into same directory where you copied the VPOP3 directory in step 1
• 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:\vpop3 to d:\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. In this case, you should also check for any possible issues with Windows/other software - see the installing VPOP3 topic for details.

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.

If you want, we can do this move for you via remote access. The charge for us to do that is currently £30 (+ VAT). If you want us to do this, make sure that it is possible to copy files between the PCs on your network (or have copied all the necessary files beforehand). Copying the files over the Internet to our office and then back again is not feasible given the large amounts of data that can be present.
