I currently have windows 10 and have been running solidworks 2015 in windows 8 compatibility mode just fine. Now, with 2016 ready for download I tried updating. Since im running it in windows 8 mode it does not allow me to complete the update because it says windows 8 is not supported. So, if I turn off windows 8 compatibility mode and try to update, It tells me there is no update available. Ive gone back and forth numerous times, rebooted, the whole 9.
Download and install from SW website, worked fine here. Windows 10, upgrade SW 2015 to 2016.
