[Curse App] [Minecraft] Error: Unable to start the MC Runtime Environment
If you get an error that states:
"Unable to start the Minecraft Runtime Environment. This is most likely caused by a corruption. Please try to reinstall Minecraft."
when trying to play a profile. Please try the following.
Use Jar Launcher
You will need to open Curse, and head to the Settings. This is the cogwheel in the lower left corner of the client.
This will open up your Settings options. Click on the Minecraft tab.
Scroll down to LAUNCH METHOD.
Change it from Native Launcher to Jar Launcher. Try which ever version of Java you have installed, if you don't have Java installed already please do so at this time. If that doesn't work:
- check to make sure you have the newest version
- try with a 64 bit version
Try disabling any antivirus programs and firewalls temporarily to see if they are blocking Curse.
Most antiviruses have a disable mode for testing things. If you can't find it you may need to contact the Antivirus Support to assist you.
If you have a router you may also have a firewall with that.
If it works when your security software is disabled, you will want to add Curse to the security softwares' white/exclusion lists. If you are unsure on how to do that you may need to contact the Antivirus Support to assist you.
Run as Admin
Check to make sure you are running both Curse and Minecraft as administrator.
You will need to go into the Curse client, and head to Settings. This is the cogwheel in the lower left corner of the client.
This will open up your Settings options. By default you should already be in your General section.
Scroll down to towards the bottom and locate RUN CURSE AS ADMINISTRATOR. Make sure it's toggled on (green).
