I cannot login to the launcher I receive a java.security.NoSuchAlgorithmException, googling around for minecraft related issues just shows people saying they have a corrupted java and to reinstall, and I know this isn't the case due to being able to make use of Curse and MultiMC, any ideas? http://pastebin.com/SW3ZMcC1
What's your operating system? You may want to try overriding your Java path in the launcher options because it might be picking up a broken Java install that you have remaining.
I'm running windows 10 I have tried running it with both JDK 1.8 and JRE 1.8 and JDK 1.7 I'm assuming the JVM path needs to be like this: C:\Program Files\Java\jdk1.7.0_45
Have you tried https://stackoverflow.com/questions/126798/java-invalid-keystore-format-error? (Deleting that file.)
Do you mind if I TeamViewer in? My Internet's bad right now so I don't know if I can do it this instance, but we could try.
It's fairly late right now in the UK so I am gonna try again tomorrow but teamviewer will probably be helpful when you can
I am UK based and I am more than happy to help you out when I can. If you can use team speak even better just let me know a time when you are normally online.
