Unclear on order of installation/patching

[Javaslinger]

There doesn't seem to be a FAQ for this...

I'm installing CMSF and the 3 add on modules. After installing CMSF it appears to be patched to 1.11. Do I think install the add ons and subsequently patch or patch to 1.21 then 1.31 and then install the add ons?

INSTALLATION DIRECTORY

CMSF Nato needs to be installed inside the existing directory where you have previously installed Combat Mission Shock Force. The installer will attempt to locate any such directory in your registry, but this is not 100% failsafe, so you should always doublecheck the suggested installation path, and correct it if necessary. The default install path for Combat Mission Shock Force is under C:\Programs\Battlefront\Combat Mission Shock Force.

CLEAN INSTALL:

Below is a brief step by step instruction on how to do a clean reinstall of CMSF. If you do not have a Module listed below, simply skip the step. Don't forget to UNLICENSE your keys on the previous PC before reinstalling on a different PC!

1- install the base game, Combat Mission Shock Force. This will typically be v1.00 or v1.01.

2- install the Marines Module. This will update your game to v1.10.

2b- use your Marines Module license key to activate. This will activate both the base game AND the module.

3- install the British Forces Module. This will update your game to v1.20.

3b- use your Britihs Forces license key to activate.

4- install the v1.21 Patch. This will update your game to v1.21. Make sure to select the correct components (modules + Base game) to update.

5- install the NATO module. This will update your game to v1.30.

5b- use your NATO module key to activate. This will activate both the base game and the module in one go.
