(Note - no version of VPOP3 will run on “Windows 10 S”)

VPOP3 version 8.0 or later requires Windows 7/2008R2 SP1 or later. It should run on both 32 bit and 64 bit Windows.

VPOP3 version 7.2 to 7.10 requires Windows Vista/2008 or later. It should run on both 32 bit and 64 bit Windows.

It has been tested on:

• Windows 2008 Server, 32 bit & 64 bit

• Windows 8.1, 64 bit (Professional & Home Premium)
• Windows 10, 64 bit (Professional)

NB - just because a version of Windows is not listed above does not mean it will not work on it, just that it hasn't been tested on it. It should work on any 32 or 64 bit version of Windows, from Windows Vista or later

Additionally, server versions of Windows may have LDAP and/or SMTP services already running. This may conflict with the services VPOP3 runs but it is easily rectified in the VPOP3 settings (or in Windows).
