System requirements for Sage 100 Contractor version 27

IMPORTANT: These are updated requirements for Sage 100 Contractor version 27

 CAUTION: We provide these requirements as a guideline for Sage 100 Contractor. We recommend discussing your specific setup with a consultant for the best performance and compatibility. 

Starting October 14, 2025, Microsoft will end support for Windows 10 unless you purchase its Extended Security Updates (ESU) program.

If ESU isn't purchased, Sage will provide limited, software-specific support for products installed on machines running Windows 10. Our support teams prioritize issues reported on supported operating systems, such as Windows 11. Problems occurring on unsupported systems may not be addressed.

To continue using or receiving full support for your Sage product, you may need to upgrade your operating system to a supported version of Microsoft Windows.
