Can't get BA 1 Mega Pack to install

[GB1957]

Hi. I bought Battle Academy (version 1) via Steam and have been playing it online no problem.

I just bought the Mega Expansion Pack from Slitherine and when I try to install it I get the message:-

"The installer cannot install the upgrade patch because the program being upgraded may be missing or the upgrade patch updates a different version of the program."

Not sure if this is being caused by buying things from different places, as I think the game is installed in a Steam folder.

I have a Windows 10 PC.

Can you help

Thanks

Graham

You can't install DLCs from one version for the other. However you should be able to create a Steam key from the slitherine serial you have. See: viewtopic.php?f=58&t=93585

I have tried to follow these instructions, but the Mega Pack has "Steam Key Not Available", so I still can't load the Mega Pack. Please Help
