Thread:Project:Support desk/Database error after installing latest version of Mediawiki/reply (7)

You need first to locate the PHP command line program on your computer. It should be called php.exe but I'm not on your computer so I have no idea of where it may be (C:\ProgramFiles\PHP may be a good point to start looking at)

Then,
 * 1) open a command prompt
 * 2) go to the maintenance directory with the command prompt
 * (assuming C:\Path\to\mediawiki\maintenance is the maintenance directory under your mediawiki installation)
 * 1) run php, passing update.php as the first argument
 * (assuming c:\path\to\php\php.exe is the full path to php.exe)
 * (assuming c:\path\to\php\php.exe is the full path to php.exe)
 * (assuming c:\path\to\php\php.exe is the full path to php.exe)
