About Uninstalling shortcut

C:\WINDOWS\system32\RunDll32.exe C:\PROGRA~1\COMMON~1\INSTAL~1\PROFES~1\RunTime\10\01\Intel32\Ctor.dll,LaunchSetup “C:\Program Files\InstallShield Installation Information{80464ABC-A520-453F-A383-6E7B92E0C3B3}\setup.exe” -l0x9

Is this normal for an uninstall file for a game? (this was the shortcut link to the unistall shortcut)
Is it normal for unistall application to require rundll32.exe, other system files and other files?

I also got this weird IME error when I exited the game, it was something like IME ERROR, with a window with just the header showing, I had to close it from task bar (if that what the line is called…) with right click and close. Does anyone know what error this is?
