Why is the system tray icon for my program not visible in Windows 7?

I'm unable to find system tray icon for my program after the installation . I could see that In Windows XP, it works just fine: the user can launch a program by clicking on the same.

However, in Windows 7 (both Home and Ultimate editions), the icon is not shown in system tray , but it works after I reboot my machine.

I ha开发者_运维百科ve tried putting the code to refresh shell icons in the installer script, but this does not seem to have fixed the problem.

Can anyone help me on this??

PS: I use NSIS script for my installer.

• Is it simply hidden in the pop-up that opens when you click the little arrow?

• If not, is your program actually running at all?

• If your program is running, use Process Explorer to check its integrity level (the Integrity column in Process Explorer). After you reboot and the icon appears, does the process have the same integrity level as when it didn't appear?
