Enigma Protector

Hi,
I don't know anything about VB, I tried to read a few posts but it just confuses me more.
What I want to do is, I believe, quite basic so maybe there's something I don't get.
I want to make a portable version of Civilization 3, an old x86 game. Something I can copy on a pen drive an carry around to play on any PC without previous installation.
I selected the main exe, which is not in the first "root" folder, but in a sub-folder (it's an expansion of the original game, conquests). I selected an output exe file, got a huge 7gb file (same size as original games's folder). Then added the whole root folders (add folder recursive), launched it and got a "can't open this file" from win 10, or something like this.
Maybe something is wrong with exe/folder selection ?
Also, am I really supposed to play the game from a 7gb file ? It's probably gonna need a lot of RAM to launch, even on a recent PC...
Thanks for answering !

There is a maximum EXE file size limit of 4 gigabytes. You can enable compression and see if it helps.

To make the exe smaller, you can put most of the files into separate package file using Packaging feature.
So your exe will be small, but the packaging file big, contains all the virtual files.

You can compress your EXE with UPX before packing it!
