I could not resist and bought the kit today ... actually 30 minutes ago. Because I've paid via PayPal I could download the files immediately (it's an electronic download only). All in all six files:
Because I still operate on Windows XP SP2 - yes, don't laugh please - I've installed the non-Windows-7-version of course. Installation went smooth ... but immediately after starting the kit I get an error from Windows:
»Shoot Em Up Kit.exe is not a valid Win32-application«
Doh? Well, maybe the supplied patch helps. But after installing it still the same error message.
I know those errors sometimes appear when you try to run a 64 bit application under a 32 bit Windows. Later one is my system. So I consulted the documentary. No hint about the Windows version. But the web site explicitly states:
»OS: Microsoft Windows XP, Vista, Windows 7 or Windows 8. 32 and 64 bit versions are supported.«
Well ... I've contacted »Tall Studio« (the makers of the Shoot Em Up Kit) ... and now I am waiting for their answer.
