Vanilla fails to install on PHP5.2.17, Windows7, Apache2.2

Hello, seems to me that Vanilla setup fails to save configuration to config.php at class.configuration.php, line 536:

chmod($TmpFile, 0775);
$Result = rename($TmpFile, $File); // Returns false.

After I modified code as follows, setup completed successfully:
chmod($TmpFile, 0775);
if(is_file($File)) {
    unlink($File);
}
$Result = rename($TmpFile, $File);

hbf

Thanks!!! this solved my problem of perpetual return to the setup screen.

@schket, I'm worried about your method because it is not atomic and susceptible to a race condition. Can you try the following:

chmod($TmpFile, 0775);
if (!rename($TmpFile, $File)) {
    if (copy($TmpFile, $File)) {
        unlink($TmpFile);
        $Result = TRUE;
    }
}

I'm proposing you try a copy and unlink the temp file rather than unlink the original file.

@Todd, I actually did not try this code in Vanilla, but I checked how rename() and copy() behave in test .php and it works right as expected, so your proposed code should work.

can someone put up the complete file so I can also use it? Better than going into the page... better to reload a completed page and rerun from there. I am having some issues of my own.

@Todd, yep, your code is working, I have just tested it.

This code will be available in 2.0.18.2. The commit is available here.
