I just upgraded to windows 10 and I'm getting this message 

The program can't start brcause MSVCP110.dll is missing from your computer. 

I followed the steps mentioned before:
1) First step is to use AVG Remover tool and uninstall your AVG program completely. To download AVG Remover Tool please click on the following link:
http://aa-download.avg.com/filedir/util/AVG_Remover.exe

2) Run the downloaded tool and follow the instructions displayed on your screen.
3) Your computer will be restarted automatically. After the restart, AVG Remover will finish the uninstallation.
NOTE: Once the AVG Remover Tool has done with its process. Please go to the C drive and look for a folder named as "AVG Remover" and I request you to delete it manually.

I also installed the C++ redistributable. 

It's still not working can you help me? 

Thanks
