Extract LegacyMULConverter into a folder
(C:\LegacyConverter is where mine is, replace this address with where you have yours)

1. Windows Key + R
2. type cmd and press enter
3. type- cd C:\LegacyConverter
(remember to change this to your Legacy MUL Converter folder location)
4. Unpacking:
type- LegacyMULCL.exe -x "E:\Program Files\Electronic Arts\Ultima Online Classic" press enter.
(remember to change this to your UO folder location)
5. Repacking:
type- LegacyMULCL.exe "E:\Program Files\Electronic Arts\Ultima Online Classic" press enter.
(remember to change this to your UO folder location)

Notes:
Legacy MUL Converter will not unpack or repack if the file already exist. Move or delete the file you're wanting to update before beginning.

I have found that the repacked uop(s) need to go into the UO folder, as well as the custom data location (if you are using a custom data location)

I leave a set of unpacked muls for UOFiddler and many other programs in a separate folder.

You do not have to use the UO Folder, you can unpack and repack into any folder that has the uop/muls.

I hope this helps. :)
