I am on Windows 7 32 Bit and MySQL starts up fine And my old version of Apache (before I was going to use the SQL database) will work fine after I get this error:

I also get this in the XAMPP console:

9:47:23 PM  [Apache]    Error: Apache shutdown unexpectedly.
9:47:23 PM  [Apache]    This may be due to a blocked port,  missing dependencies,
