 =====64 bit version=====
-Starting with VPOP3 v7 we are also releasing a 64 bit version of VPOP3. To upgrade to the 64 bit version, you must previously have been running v5 or later.
+Starting with VPOP3 v7.1 we are also releasing a 64 bit version of VPOP3. To upgrade to the 64 bit version, you must previously have been running v5 or later.
-The 64 bit version of VPOP3 does not include some library components which are needed to read data from v4 or earlier, so if you upgrade from v4 or earlier to 64 bit v7, then you may lose some data during the upgrade. So, if you are using VPOP3 v4 or earlier, we recommend upgrading to a recent 32 bit version of VPOP3 and run that for a week or two to let it complete any background data migration, then upgrade to the 64 bit version of VPOP3 if you wish.

+The 64 bit version also lacks some features of the 32 bit version:
+  * The Webmail interface doesn't have a spell checker
+  * Sophos SAV Interface (SAVI) does not work
+=====Problems during upgrade=====
+We recommend that if you have any problems during the upgrade, you contact us immediately (01484 855800). Do not try to 'fix' it yourself unless you are sure of what you are doing (and have a known-good recent backup), as that will often cause even more problems. We do not charge for problems that occur during the upgrade or installation process.
+====Error 1031 during installing the database====
+Check that the password for the Windows user 'vpop3postgres' in Windows is set to **Nc6ACboDt2jVL6**. This is the default since version 5 was released, but sometimes people have changed this. The installer needs to run some programs as the vpop3postgres user, so it needs to know the password. If the password for this user has been changed, then it will be unable to run the programs as this user.
+**Do not abort the VPOP3 installation!** Instead reset the password in Windows, then tell the installer to retry the operation
+====If you do abort the installation====
+If you abort the installation for any reason, before the 'pg_upgrade' window has appeared as described above, then it is possible the database folder has been renamed so the database will not work.
+To put back the old database, you need to rename some folders and reinstall VPOP3 version 6.x
+  - Stop the VPOP3 and VPOP3DB services in Windows (if they are running)
+  - Rename the **VPOP3\pgsql** folder to 'pgsql_old' (or similar)
+  - Rename the **VPOP3\pgsql91_v7upg** folder to **pgsql**
+  - Reinstall VPOP3 version 6.20
