In Today’s ever connected world Avoid surprises by checking all software compatibility Prior to any act! Upgrade


Office 2010 and earlier is no longer supported with act!
Google Chrome support was certified with Act! v21 & v22
Sql 2008 has been discontinued
Windows 7 is no longer supported


Some clarifications:

It is time.  Some older workstations and servers must be retired.  These Act! System Requirements are not really about Act!, it is Microsoft that has led the way in retiring this older software.  Your risk is that the older software is no longer being updated by the manufacturer.  What this means is that as new security risks arise, you are no longer getting updates to combat them on the older versions of software.   



You will need Office 2013 or higher,  if you want to use Office with Act!  Also note that the Office installation is done prior to the Act! installation.

Please note the removal of SQL 2008 from the supported list of Operating Systems.  This leaves the following as valid:

  • Windows Server 2019
  • Windows Server 2016
  • Windows Server 2012 R2
  • Windows Server 2012
  • Windows 10 (32-bit and 64-bit)
  • Windows 8.1 (32-bit and 64-bit)

Also note that Act! uses SQL Server® 2014 Express or your existing installation of SQL Server 2012 or newer.  Express is free, but limits processor use to the lesser of a single CPU socket or 4 cores. Memory is also limited to 1 GB, and the size of your data file cannot exceed 10 GB.


In the past, most Act! Add Ons were written using the Act! SDK.  These Add Ons were designed to be locally installed.  This meant that they operated locally installed on a system, or were enabled on a machine that would Synchronize to a Web based install.  With Act!’s move to a SAAS environment with no synchronization, Add Ons will now need to be developed using the Act! API so that they can operate without Act! being locally installed.  Make sure to check with your Add On vendor before your move to SAAS to make sure they have developed this functionality – Avoid Surprises!
