System Requirements


The specifications indicated here are our recommended minimum requirements. We suggest obtaining as much RAM, processor speed and hard drive space as is possible for the best performance in running ESC and all Windows applications.

Server / Demo Requirements

  • Windows .NET Framework 4.7 or later must be installed prior to upgrading to ESC 15.1
    • Download the latest Windows .NET Framework, directly from Windows, click here
  • Maximum resolution of 1080p at 100% DPI
  • 2.0 Ghz Quad Core Processor or faster (2.6 Quad Core Ghz or higher recommended)
  • 8 GB Memory (16 GB or higher recommended)
  • 10 GB or more available hard disk space (Solid State Drives recommended when using ESC
  • Accounting and for larger databases)
  • TCP/IP – Over a Microsoft Windows Domain or Workgroup
  • Windows 8 Pro, Windows 10, Server 2008 & 2012
  • Internet Explorer 9.0 or later, current Virus Protection software
  • For Quickbooks or Sage Integrations: A full version of Quickbooks or Sage software must be installed on the server. See Accounting Integration Requirements, below, for more details.
  • Optional: ESC includes Microsoft SQL Server 2012 Express as part of the installation. If you want to replace this with your own version of SQL, you will need Microsoft SQL Server 2008 or later.
  • Note: While it is possible to install, connect and run ESC in the following environments, dESCO does not have the technical expertise to provide users with any assistance or support for problems encountered using them. These environments include:
    • Terminal Services
    • Virtual Private Networks (VPNs)
    • Remote Connections
    • Citrix Server
    • Dual Boot MAC Operating systems
    • Virtual Installations
    • Hosted Exchange
    • Microsoft Exchange Server

SQL Express Database Limitations

  • Microsoft SQL Server Express limits server memory usage to 1GB. This limitation can disrupt desktop and mobile connections to the database in larger companies (defined as 10 or more desktop users and/or 20 or more mobile users) should consider a full version of Microsoft SQL Server 2008 or higher.
  • Microsoft SQL Server Express has a database size limit of 10GB. A brand new database will start out at approximately 8MB, giving plenty of room for growth and may take several years to approach the limit. However, attaching documents to customer records will increase the size of your database more quickly and may bring your database to the limit faster.

Workstation Requirements

  • Maximum resolution of 1080p at 100% DPI
  • Dual Core Processor or faster
  • 4 GB Memory (8 GB or higher recommended)
  • 2 GB available hard disk space
  • TCP/IP – Over a Microsoft Windows Domain or Workgroup
  • Vista (SP2), Windows 7 (SP1), Windows 8 Pro, Windows 10 or Server 2008 & 2012 - 64 bit versions recommended
