you don't know what a subfolder is?
you must be new to handling a pc i guess?
okay, let's do babysteps, shall we?
number 1: create a folder somewhere on your harddrive that you can easily find by clicking with your right mouse and then on creating a folder. we will call it "the company".
number 2: we will now download base image pack v11; HTML 6.0.3 and the patch Image Pack update (v11 => v11e). put everything you download into the created folder called "the company".
number 3: extract the image pack with 7zip or winrar. if you don't know how, tell me and i will guide you through.
you should now see a folder "pics". this is the actual subfolder of your mainfolder "the company". subfolders are folders within a folder. sao bascially, if you have a folder inside the "subfolder" pics, it would be the subfolder of pics ^^.
number 4: extract HTML 6.0.3 with 7zip. you should get an HTML file out of it. it has to be next to the subfolder "pics". don't place it inside the subfolder, it just needs to be next to it.
number 5: extract the patch image pack update. if you unzip it in the same folder as the others you will get asked if you wanna overwrite the folder pics and maybe some images. simply click on: yes, overwrite everything.
number 6: delete all zip files and start the game by clicking on the HTML file. your webbrowser should handle it now.
