Microsoft Visual C++ Runtime Library

Hi guys,
Have a look at the error message below. This is the only problem with my browser Opera.
For a moment, Opera stops working throwing the error message. For this reason, my online applications become distorted.
If you have an idea for the issue, please help.
Thanks in advance.

Microsoft Visual C++ Runtime Library
