Hi,
32-bit version won't run due to architecture mismatch. Make sure everything in its path is 32-bit.
Without having your project (source code + assets) I can't guess why it's showing a blank screen. Please attach a download link to your project so I can take a look. You can register for free to the forums, there you can attach files and benefit from the Tilengine community:
