Notepad++.exe System Error in Win7

Hello,
I use windows 7 ultimate Operating System. When I tried to open text files using Notepad++, I have found a problem. Then I am getting the following error:
"The program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix the problem".
I try to reinstall Notepad++ but the same error occurred again.
Note: After clicking OK or X, the program worked generally but I want to erase this message.
I really need a solution. Thanks a lot for any help that may come along.
