Tiled 1.1 x64 Problem!

When installing Tiled 1.1 x64 build I got this problem and I’ve got no clue how to fix it
Any help?

You’ve probably upgraded from Tiled 0.18.1 or older. Unfortunately for 0.18.2 I’ve made a change in the MSI installer that broke upgrading from any older versions. Upgrades from 0.18.2 or newer at least work fine though.

You should be able to resolve the problem by explicitly uninstalling all versions of Tiled listed in “Add Remove Programs” (or however Windows calls this now), and then installing Tiled 1.1.0 again.

Sorry for the trouble.
