You will notice in the MD5 field the value ea26f19d4b77606971885745ae0ce4db  This is the MD5 checksum value.

2.  I can compare the MD5 checksum value with another file to see if they are the same.  Press the Compare button this will allow you to select a file to compare with:

In this case, I will select the same file SetupMD5.exe

You will notice that MD5 checksum value of the file I just selected turned green.  This indicates that the files are the same.  If I were to select a file that was slightly different, it would have turned red:
