Microsoft® Operating System Compatibility
Over the years, both On Center Software/ConstructConnect and Microsoft have developed and released new versions of their software. The grid below indicates which versions of On Center Software's products are compatible with various versions of Windows. For our policy on which versions of our Classic products are supported and for how long, see CLS - Product End of Life (Sunset Plan).
On Center Software supports our software installed and operated only on versions of Windows currently under "Mainstream Support" with Microsoft. When a version of Windows is moved off of Mainstream Support (retired) by Microsoft, products that were limited to installation on that operating system (or earlier ones) only are no longer supported by On Center. Products limited to Windows versions that fall of "Extended Support" with Microsoft will no longer be distributed.
If your version of On-Screen Takeoff or Quick Bid is no longer supported or is limited to a Windows operating system version that is no longer supported by Microsoft, please contact Customer Success at 866-627-6246 to discuss your options.
On Center products are designed for and tested on US-English versions of Windows®. There may be minor display issues when installed on other regional versions of Windows.
On Center products are designed for and tested on Professional and Enterprise editions of Windows®. We do not test on “Home” editions or other non-business-level editions of Windows and cannot guarantee that you will be able to install or run On-Screen Takeoff or Quick Bid on any editions of Windows other than Professional and Enterprise.
"Server" operating systems should not be used as a Desktop operating system - they are not designed for this function. The applications are not tested nor certified when using any Windows "Server" version as a desktop, personal computing operating system. Server versions are listed here for clients using Remote Desktop Services to 'publish' the products through virtual desktops. Server operating systems may display some parts of a program's interface a little differently (menus, toolbars, etc.) which does not affect the overall usability or functionality of the program.
If you are planning on upgrading your operating system (say, from Windows 8.1 to Windows 10), you must return all product licenses and uninstall On-Screen Takeoff/Digital Production Control and Quick Bid before installing the OS upgrade. Once you have completed the OS upgrade, run Windows Update several times to ensure your Windows OS is fully-updated. Then reinstall OST/DPC/QB and re-license.

*On January 14, 2020, Microsoft ended support for Windows 7 and Server 2008, it is no longer a "Supported" operating system and On Center/ConstructConnect products limited to this version of Windows are no longer distributed or supported. See: Microsoft's Product Lifecycle FAQ for more information: https://learn.microsoft.com/en-us/lifecycle/.
**Windows 8, Windows 8.1, and Windows Server 2012 are no longer under "Mainstream Support" with Microsoft, effective 1/9/2018 and are no longer tested on new versions.
***Rigorous testing has not been done on Server 2016 or 2019, these are server operating systems and are typically not used for desktop operating systems. You may be able to "publish" On-Screen Takeoff and Quick Bid using Remote Desktop Services, although that is not a task with which our Support Team would assist.
**** On-Screen Takeoff 3.98.06.19 and newer, using Access databases, is supported on Windows 11. We have not certified SQL databases yet, although there's no technical reason they shouldn't work.
