Firstly, please do make your own threads for your unique issue, rather than posting on someone else’s thread. Otherwise, things can get confusing. I have split your post into its own thread.

It like vanishes from task manager even the logo doesn’t show up

Some more things to try:
-
Run with administrative rights (right click icon–>properties–>compatibility tab–>check box for admin privileges)
-
Run in compatibility mode for Windows 7 (right click icon–>properties–>compatibility tab–>check off ‘run this program in compatibility mode for:’–>select Windows 7 from dropdown list)
- Verify .NET Framework 3.5 is installed: search for ‘Turn Features on or off’ in Windows search in lower left corner:
Make sure the highlighted box is checked off or filled in:
