I donwload the zip archive. The create a foldet C:\ Msys. Extract all the contents from the zip archive to the folder. Following the Read Me instructions, I click on the msys shortcut. A dos window opens then I get an error message  headed "16 bit MS-DOS Subsystem" that reads: " C:\Msys\msys\msys.PIF imvalid program file name, please check your  pif file. Choose 'Close' to terminate the application." I am then only able to close the application. Any ideas?
