Manager not open why?

The program was working well but now when i click on the ICON program does not open ??
Please what problem

What operating system? What operating system version?
Did you do an update?
Did you install any other software?

The bottom line is that something changed. Until you figure out what is different, no one can help you.

I use Windows 10
I install Microsoft Office 2010
It has been received Office 2010 updates
When you click on the program does not change

I realize that if you cannot open the program you may not know what version of Manager. But do you possibly recall the version number? If not, how long ago did you install it?

Did you move any Manager files? Did you install the program anywhere except in the default location?

I use the latest version of Manager

Is is possible to be more specific? Manager advances very rapidly, sometimes with multiple releases in a single day.
