Very strange bug with AIR and native process (Windows 7, EXE)

Hello to everyone!

The situation is:

I've made an AIR Application, inside of that is running a native process - EXE file.

I'm using Flash CC as IDE and tried to use compile that as EXE with AIR 2.6 and 3.6 - results are same.

So I've insert inside a checking if Native Process is supported or not and the Native process is supported all the time.

When I've just installed the application and run it - the very first attempt is good - everything is working as a must: internal EXE is called by my Application with necessary parameters as many time as I'm need.

However if I'll close the App and then will run it again - internal EXE is not starting at all, doesn't depends on number of attempts to re-start of the App.

So only way is to uninstall, install it back and then you'll be one more session of successful internal EXE-requests, till the next re-start of the App.

That's it.

I've tried to "google it" but unsuccessful. Probably the bug is very rare.

Help me please?

Update: at compilation with Flash CC IDE it's working all the time with no any issues.

Update-2: when I'm running installator-EXE, there is going a notification "Same version is installed, etc." and then selected "Run Now" - there is also working with no problems.
