Incase people still need to change their installation folder to be able to play. I found a bit of a workaround for this problem since I can not stand things installing on my OS drive, and wanted it on my game drive.
First I went to "Q:\Program Files\Outspark\OutsparkLauncher\rb\OutsparkGlobals .rb" This just happends to be the location I installed the launcher, so just go to where you installed the launcher, the rb folder and look for the file OutsparkGlobals.rb. Make a backup of the file incase you make a mistake. Then open the original file in notepad. Look for def get_appdata_path(). Under it will say appdata = "". Between the quotes add the path you would like to install to.
Mine looks like this appdata = "q:/Outspark" But use whatever path you would like to use. Make sure the drive you are putting it has at least 1.75gigs free, I would still say at least 2gigs to be safe though.
Make sure the quotes are still there and you use a / not a \. Such as "d:/Games/Outspark"
Now under the line that was just changed, there are a few lines that now need to be removed to make this new path work. Remove everything under the line we just changed until you get to the line appdata.gsub!("\\", "/"), leave that line and then save.
You are still going to need about 600megs free for the download file since it wants to put that in a temp dir on same drive your OS is installed. There is another workaround I did for this, but it gets to involved and it should be easy enough to make 600megs free for just the install file, rather then over 2gigs for the install and then game.
Open the launcher, and it should start Downloading the game. After the Download is done it will now install to the new path. Everything worked for me doing this, and playing the game on my games drive where it belongs
