Several AcroRd32.exe processes

[yevheniiy81221888]

I opened one instance of Reader and get the two same processes.

Process.Start(...) do the same thing and returns window handle which is NULL but second process has correnct HWND

 Is that should work in that way?

This is by design if the "Protected mode" option is on.

The first app has no HWND or interface, but can access all files.

It starts the second app in a sandbox, which can access no files. It has all windows and HWND.

The first app controls access to files for the second app. This is called "Sandboxing" and many apps now do this, especially web browsers.
