2) Select Menu | View | Option | File Types

3) Now select the New Type... button

4) Enter the description as something like 'Makesis Script File', and the associated extension should be PKG

5) Under the Actions area, click the New... button

6) In the resulting dialog, the Action should be 'open' (without the ' marks) and the Application used to perform the action should be entered as notepad.exe "%1" - enter it exactly like that, INCLUDING the " quotes around the %1. Click OK

7) Now add another new action, this one should be called 'Compile'. The Application used to perform the action will differ depending on whether you have Windows NT or Windows 9x....

* On Windows NT, you should enter cmd.exe /c makesis "%1" - again, be sure to include the " marks around the %1

* On Windows 9x, you should enter command.com /c makesis "%1"

8) Click OK to that dialog, and then Close on the other dialog. Finally click Close on the main 'File Types' dialog too.

That's it. Now, you will be able to double click on PKG files to edit them in Notepad, but also right click and then select 'Compile' to automatically compile them. The output SIS file will be placed in the same folder as the PKG file using this method.
