Lost drivers - Fn keys no longer working

KYRON

I tried to install an XP game and PC crashed. I reset the PC but all the drivers are lost. 

Then I downloaded the drivers from ACER websie and when I run the setup I get an error message

 

The program can't start because MSVCP110.dll is missing from your computer. Try reinstalling the program to fix this problem.

 

I am frustrated, please help.

 

Thanks
