Troubleshoot MCR Files

Common MCR Opening Problems

Minecraft Isn't There

When trying to open your MCR file, you get the error "Can't Open MCR File Type". Customarily, this means that Minecraft is not installed on %%os%%. This will prevent you from double-clicking to open the MCR file because the OS doesn’t know how to handle it.

Tip: If you know of another program that can open your MCR file, you can try opening it by selecting the application from the programs listed.

Obsolete Version of Minecraft

Your Minecraft Region File file is incompatible with Minecraft because you might have the wrong version installed. Download the latest Minecraft version from the Mojang website to ensure you have the correct one installed. This problem is predominately due to having a Minecraft Region File file version that was created by a newer version of Minecraft than what you have installed on your PC.

Tip: Sometimes you can get a clue about the version of MCR file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Conclusion: The majority of MCR file opening issues are due to not having the correct Minecraft version installed.

Other MCR File Opening Causes

In the majority of cases, installing the right version of Minecraft will resolve your issue. Other MCR opening errors can be created by other system problems inside of %%os%%. Other contributing causes:
