I have been using Silverstripe 3 but needed to download version 2.4.7 on MAMP to access some of the existing modules. Unfortunately, I keep coming up against the same problem when I try to install the program. The message I get is:

[User Error] Couldn't run query: SHOW FULL FIELDS IN "SiteConfig" Table 'ss_mysite.siteconfig' doesn't exist
POST /SilverStripe-v2.4.7%202/install.php

Line 525 in /Applications/MAMP/htdocs/SilverStripe-v2.4.7 2/sapphire/core/model/MySQLDatabase.php

No doubt, I'm quite dim and missing something obvious... but can someone point me in right direction?

Thanks.
