Does System Mechanic 16 Support Windows XP and Vista?
As System Mechanic® advances its core technology to keep pace with the major changes to Windows® beginning with Windows 7, the new software architecture that makes its debut in System Mechanic 16 is not compatible with Windows XP and Vista.
While System Mechanic 16 focuses on fully leveraging Windows 7 through 10, a special version of System Mechanic for Windows XP and Vista has been designed to clean, stabilize and speed up these older operating systems, and is the best option for XP and Vista users. Windows XP and Vista users should refer to the Knowledgebase folder System Mechanic for Windows XP & Vista
for answers to product questions.
If you are running Windows XP or Vista and you attempt to install System Mechanic 16 designed for users of Windows 7 and above, you will receive an install error message.
