[Help installing modules after V4 upgrade]

I added the PS, because before installing v4, the version that was being used was a patch of v2. So my dad purchased the V3+4  upgrade bundle for $15. But when i looked at the file I only saw the v4 installer, and couldn't see the v3.

I upgraded fine to v4, but it didn't have the installed modules, and was just a v4 of the standard game. Then I re-installed the Market Garden/Commonwealth modules (which i now understand was incorrect) and it took it back to a basic v1.2.

What i am having trouble with is essentially adding the modules back to the game whilst also playing v4 and i have no idea how to use the current disc/downloaded files to do that without purchasing anything else.

[Help installing modules after V4 upgrade]

I'm trying to help my dad with CMBN installation.

Here are the separate file components he had;

- CMBN disc

-CMBN Commonwealth Forces Disc

-CMBN upgrade V2

- CMBN Operation Market Garden Disc

- CMBN Upgrade 3+4 Windows bundle Downloaded files.

After having trouble downloading version 4, I finally managed to get it installed, however his two add on modules were not present. I read some of the forum and tried to figure out how to do it. I understood that they needed to be reactivated, yet I couldn't find the activate modules shortcut, nor could I find it when searching the files on the computer.

I need help on how to keep the v4 upgrade, but also how to install/activate the Market Garden/Commonwealth modules.

Thank you

P.S. Whilst looking through the files, i could only see the v4 upgrade, and no v3 upgrade.
