I have an iMac G4 1 ghz with 62 GB left of hard drive space. I have just recently installed The Sims on here (OS 9 version) and I have the Livin' Large expansion pack (also OS 9) so I tried installing that, too. However, it gave me an error message saying that an additional 423.9 megabytes were needed to install. I know I have more than enough space left and I was wondering what the deal is here. I have installed other games on the computer after I tried putting Livin' Large on here and they've installed fine. So what do I need to do in order to get my version of The Sims to update to Livin' Large? Thanks for any help in advance.
