Microsoft Visual C++ - Runtime Library

When I try to open RoboHelp(6) I get this message:

Microsoft Visual C++ Runtime Library
Runtime Error!
Program: C:/program Files/Adobe/RoboHelp 6.0/RoboHTML/RoboHTML.exe

This application has requested the Runtime to terminate it in an unusual way.
Please Contact the application’s support team for more information.”

If I click OK, it closes the application?

What can I do to fix?

Thanks
