You have to modify some registry values.
The Inno Setup FAQ http://www.jrsoftware.org/isfaq.php#assoc describes how:
[Registry]
Root: HKCR; Subkey: ".myp"; ValueType: string; ValueName: ""; ValueData:
"MyProgramFile"; Flags: uninsdeletevalue
".myp" is the extension we're associating. "MyProgramFile" is the
internal name for the file type as stored in the registry. Make sure you
use a unique name for this so you don't inadvertently overwrite another
application's registry key.
Root: HKCR; Subkey: "MyProgramFile"; ValueType: string; ValueName: "";
ValueData: "My Program File"; Flags: uninsdeletekey
"My Program File" above is the name for the file type as shown in Explorer.
Root: HKCR; Subkey: "MyProgramFile\DefaultIcon"; ValueType: string;
ValueName: ""; ValueData: "{app}\MYPROG.EXE,0"
"DefaultIcon" is the registry key that specifies the filename containing
the icon to associate with the file type. ",0" tells Explorer to use the
first icon from MYPROG.EXE. (",1" would mean the second icon.)
Root: HKCR; Subkey: "MyProgramFile\shell\open\command"; ValueType:
string; ValueName: ""; ValueData: """{app}\MYPROG.EXE"" ""%1"""
"shell\open\command" is the registry key that specifies the program to
execute when a file of the type is double-clicked in Explorer. The
surrounding quotes are in the command line so it handles long filenames
correctly.
One can of course modify the same registry values using a python program.
