On Center Software is committed to providing award-winning products and services. To that end, we must occasionally take an inventory of our product versions to determine those that need to be retired (or ‘sunset’). On Center remains focused on current technology and advancing/improving our software - that cannot be done if we continue to support out-dated versions of our software. So to help you, our clients, understand which products are supported, we developed this "End of Life" Plan.


On January 9, 2018, Microsoft ended "Mainstream Support" for Windows 8.1, therefore On Center Software will no longer test new releases against that platform. On Center will provide minimal technical support for Windows 8.1 until January 10, 2023, when Microsoft ends "Extended Support" for that platform. 

On January 14, 2020, Microsoft ended support for Windows 7 (and Server 2008/S2008 R2). Versions of On-Screen Takeoff, Quick Bid, and Digital Production Control limited to Windows 7 or earlier are no longer supported or distributed. See Microsoft's article about Windows 7 End of Life: https://www.microsoft.com/en-us/windows/windows-7-end-of-life-support-information.

Also, Microsoft previously ended all support for Windows 8. Your must upgrade to Windows 10 to install current releases of On Center's products. Any time you are upgrading your Operating System (from Windows 8 to 8.1 or Windows 8.1 to 10, etc.), we recommend that you uninstall OST/DPC/QB before upgrading. Windows does its best to migrate programs but it is best practice to remove any business-critical programs (such as OST/QB) and freshly install them after applying the OS Upgrade.

On Center regularly updates our System Requirements for the current versions of our products and it is important to check the latest System Requirements before installing any software, (see Related articles).

If your software version is no longer on support or has been pulled from distribution, please contact our Customer Success team at 866-627-6246 for information on migrating to a supported version of your software.

Products limited to "retired" versions of Windows

Microsoft has a two-stage retirement plan for its products. First is the end of "Mainstream" support, the second is the end of "Extended" support. See Related Articles, below, for a list of all supported versions and operating systems.

  • Mainstream Support: When Microsoft officially ends "Mainstream" support for an operating system, we no longer test new products on that operating system. You can continue to use versions limited to these operating systems, however On Center's ability to provide technical support for those product versions is limited to licensing the product and providing basic troubleshooting assistance. Advanced technical support including defect reports, crash-troubleshooting, and installation issues are not supported for products limited to running on any version of Windows that has fallen off "Mainstream" support with Microsoft.
  • Extended Support: When Microsoft officially ends "Extended" support for an operating system, On Center considers products limited to installation on that version of Windows (or earlier) retired. Products limited to operating systems that fall off Extended Support will no longer be longer distributed by On Center. On Center will not provide technical support for products whose installation is not tested and supported on "unsupported" versions of Windows. This includes licensing, installation (including product downloads), and any issues, concerns, defects, or feature requests.

  • On January 13, 2015, Microsoft ended "Mainstream" support for Windows 7. Effective that date:
    • On Center stopped testing new products on Windows 7. You may ask "Will new products continue to work on Windows 7?" Probably not, newer versions may require Microsoft system components that are not available on Windows 7. We definitely do not recommend using any "expired" operating system. Updates to software version originally supported on Windows 7 will work, however. 
    • If you call Tech Support to report an issue, if the issue is considered to be due to Windows 7, we would not be able to log a defect, investigate the cause, or work on fixing the issue.
    • Support cannot assist with installing or troubleshooting the products on an Operating System that is not under mainstream support, although we can provide you with the links to download the software and provide general assistance with using the product.
  • On January 14, 2020, Microsoft ended “Extended” support for Windows 7. Effect that date:
    • On Center no longer distributes or supports any versions of the software that are limited to installation on this OS. (There will be no way to download these versions from On Center's site - there will be a short delay, of course, to allow our existing clients to download installers.)
    • On Center Support will no longer provide assistance with troubleshooting versions of the software limited to Windows 7. See our Windows Compatibility list in Related Articles, below.
    • If you call Technical Support with any problem with a version that is no longer supported, our Support department will do their best to assist you, but the answer may be 'you need to upgrade to a newer version of OCS software' or even ‘you need a new operating system’. You can contact Customer Success at 866-627-6246 to discuss your options.

How Does This Affect You?

Now, you are probably going to ask, "Will my software simply 'stop' working on the date Microsoft ends Mainstream Support or Extended Support?" No, of course, not. In fact, it is likely that nothing is going to change except that On Center will no longer be testing new releases against that operating system, nor will we register new ‘bugs’ that can only be reproduced on that operating system.  On Center will also not support installation of products on operating systems not under “Mainstream” support with Microsoft.

However, when Microsoft ends "Extended Support" for an operating system, they stop publishing security and OS updates. That puts anyone remaining on that OS at risk and you needs to migrate/upgrade to a supported Operating System. This means you will likely have to install upgrades to your On Center products. If you are off-maintenance, or have been, you may be required to renew your maintenance subscription or even purchase new licenses. Contact Customer Success at 866-627-6246 to discuss your options.

What can I do if the version I’m using is no longer support?

This depends on if you kept current with your Maintenance agreement with On Center Software.

  • If you have remained current with your Maintenance Subscription (and are using a supported Operating System), we have versions of our Classic Products ready for you. Please contact Customer Success at 866-627-6246 for assistance upgrading to the latest versions.
  • If you have allowed your Maintenance Subscription to expire, your Maintenance contract's expiration date determines the highest version of the software for which you are eligible. On Center may no longer distribute a version of your product that will work on the version of Windows you are using. Also, the version of the software for which you are eligible may not work on newer operating systems (for example, you cannot install some older versions of On-Screen Takeoff on Windows 10 - the operating system wasn't around when those versions of OST were built/released and their installation will likely fail. You’ll need to discuss your options with Client Services at 866-627-6246.
