The Window System above Win10 that has been updated can open the new version of KTflash normally. If the update is not turned on, the new version of KTflash will not be opened, because the new version of KTflash will rely on a higher version of Microsoft Edge browser. ECUHELP team made a solution and instruction document for this situation. 

1.Open the KTflash installation directory



2.Run Microsoft EdgeWebView2 repair tool.exe. 


3.Click One-click repair, wait for the repair to complete, and restart the computer to run KTflash.
