Hi Guys,
I've been getting a few of these MSI related installer issues, so I have decided to throw the whole MSI nonsense in the bin and create a brand new installer with NSIS. The great news is that I have tested the new installer and it's much faster to install AppGameKit and get this, it goes from 344MB down to 119MB in size for the same content. Don't ask me why, because I WILL tell you, and Microsoft won't like it.
The new installer is uploading now and should be live by early Wednesday. Hopefully this avoids any more annoying uninstall/reinstall nightmares.
A WORD TO THE NEW: Remember to make a full back-up of everything you hold dear before updating your dev kit, and it's probably not a good idea to update during a time critical project too.
I drink tea, and in my spare time I write software.
