Hallo, Faith! I'm sorry you're having problems installing the game!
If you're on a PC, just go to the download page and click the FIRST download button. If you have a MAC computer, then go down to where it says "MAC Download".
If you have a PC, and the download is giving you some trouble, you might want to try the Torrent.
Can you explain to me a little more what you mean by you can't install it? If you are meaning that it isn't working, can you maybe elaborate on it a bit more on when it's giving you problems? I'd love to help but it would be easier for me to understand just what the issue is you're having here :)
Just gonna add a single tidbit here just in case.
There's been multiple claims of Google Chrome labellin' the download as malicious 'n blockin' it from many users' computer softwares. I assure ye' that the download is completely harmless and that Chrome is bein' simply paranoid since the download is an uncommon one. Therefore, I advise ye' to try downloadin' the game on a browser such as Internet Explorer or FireFox.
There's also one's own anti-virus system to keep in mind for it can be just as paranoid as Chrome sometimes. If yer anti-virus is labellin' the download as malicious and restrictin' ye' from the game, the solution would be to lower yer firewalls temporarily as ye' download the game and/or excuse the program from yer anti-virus altogether, make it an exception.
This is all I can offer unless given further detail on the matter here. Feel free to give Ms. Vask 'n I a nudge if our suggestions work naught.
