Minecraft Installer overrides Scrolls installer

If you use the Scrolls installer to install Scrolls, then install Minecraft, Scrolls gets removed file-wise.

Replication:
1) Install Scrolls
2) Confirm C:\Program Files (x86)\Scrolls exist with the ScrollsLauncher.exe
3) Install Minecraft
4) C:\Program Files (x86)\Scrolls does not have the ScrollsLauncher.exe anymore.
