beamer error for .sty file

I am trying to make a beamer presentation but an external error that I don’t know comes up in the name pdftexcmds.sty. This error comes even for starting a quick beamer from wizard. This error is not from the program but a package or LaTeX error. This is the error I got :

C:UsersmkluwAppDataRoamingMiKTeX2.9tex/latex/pdftexcmdspdftexcmds.sty : Undefined control sequence…..

When I click the error it shows a different program .sty file with the name pdftexcmds.sty and I cannot also run this .sty file.

log file of the error part:
