I am installing a clean install of XF RC2 on my local pc(yes 2 first, then I'll upgrade to 3...to mirror the process I used on my live server). I followed Brogan's guide for setting up XAMPP on my Windows XP machine, and all went well up to a point. Step 1 Welcome, Step 2 Verify Configuration went fine, and I am stuck on the third step Install. My browser says "Rebuilding...Core Master Data". It has been there for 10 minutes, so I pressed the Rebuild Caches button below it, and it is still stuck there after 10 minutes. I tried rebooting but the install process becomes stuck at the same place. The only note is the first time I began the install process I missed changing the permissions on the data and internal_data folders. I caught the mistake, unchecked "read-only" default setting, but the issue remains.
