Thanks for this installer, it's a great way to get going fast.
I couldn't work out why the graphics tests were failing. Then I did a configuration change which failed, highlighted that the pathname was too long or had spaces.
The default install folder is c:\Program Files\Typo3xxxx. Changing this to c:\Typo3 solved the problem.
I downloaded Type3Winstaller, doubleclicked it (it installed everything), and doubleclicked afterwards Typo3Starter.exe, which resulted in error messages (see below). Is there more to do than just double-clicking? Adjusting some config files?
