Have found and tried multiple workarounds trying to turn off KB3072630. Tried temporarily disabling the security fix via DWORD value and the disable.reg. I also tried installing as an administrator and running in windows 8 compatibility mode. Has anyone had any success installing to windows 10?
The version of the service pack that installs initially from the disk is SP2.1.
You cannot install general SDK 2015-2016 version on Windows 10 because of incompatibility between SWx and OS Win 10.
2015 SP5.0 is the first supported version for Windows 10, and SDK is SP2.1 as you wrote. Our customers (students) resolved it by use Compatibility mode (Windows 7) > RMB on SolidWorks icon > Properties
Hope it helps
Welcome to the forum. What version and service pack of SolidWorks are you trying to install?
