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:\Users\mkluw\AppData\Roaming\MiKTeX\2.9\tex/latex/pdftexcmds\pdftexcmds.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:
