Click on start, Search, All files and folders. Then type SPGRMR.dll in the top box, and Look In C: Drive then click search, it should be located in Windows ime a 62kb file. If it's there right click on it and Open Folder Containing. It maybe corrupt you can try SFC /Scannow or download and replace the corrupt one click here.
