iGoldMine and iHeat both have downloadable Mac clients but Windows IIS can be sniffy about giving your users access to them.

This is because Windows has no idea what ‘.dmg’ files are and so refuses to acknowledge their existence.

The result is that users get an ‘iGoldMine.dmg file not found’ error when they try to download it.

The solution is to go into the Properties of the iGM or iHeat website, select the ‘HTTP Headers’ tab, and then add a new MIME type for .dmg files: application/octet-stream
