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  Your risk is that the older software is no longer being updated by the manufacturer.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 2022
  • Windows Server 2019
  • Windows Server 2016
  • Windows Server 2012 R2
  • Windows 10 ( 64-bit)
  • Windows 11 (64 bit)


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!
