Creating custom modpack

[BloodDrunk]

Hello
Im trying to create a custom modpack (MC version 1.12.2) but it seems like im failing the forge part because i keep getting the "Server has mod that require FML/Forge to be installed on the client" error

I have looked and what feels like every guide but still no luck. 
Im trying to work off this one at the moment but i cant seem to run the forge universal.jar file. I click it and nothing happens. (step 4. Run the installer you just downloaded.)

I have also tried taking the universal.jar i downloaded from forge and renaming it to modpack and putting it straight into bin file, but still no luck.

This is the link of the modpack i am using for the technic:

Don't use the universal, rename the installer "as-is", no extracting.
