I think i had the same problem try to install java i will send you a link
http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

Hi lazaresco, try doing the following:

- Download the most recent version of 64-bit Java (x64) from the link Bombik posted above,
- Wipe "Westeroscraft" from %appdata%/roaming or Library/Application Support, depending on if you have macOS or Windows,
- Redownload the launcher

This should fix it.

O Well, Got it working after a while. The problem for me was after I updated the launcher I closed it and reopened it for it worked.
Thanks anyways.

When I click Launch Minecraft the button turns grey and then goes back to normal and nothing happens what is my problem?

 

[Emoticone11]

@Jollan20 Go to the "Log" tab in the launcher window. Can you copy/paste what it says into [spoiler][/spoiler] tags?

 

[Jollan20]

It says this: Cannot run program "C:\Program Files (x86)\Java\jre1.8.0_45\bin\javaw.exe"

 

[Emoticone11]

Try making sure you have the most recent version of Java installed, also make sure to get the x64 version.

See the directions I posted above in this thread.

 

[Jollan20]

Is it safe? I mean when I install the new version of java it tells me to uninstall the old version and that there may be programs that will not be able to be runned when I uninstall the old java...

 

[Emoticone11]

If you install the most recent released version you shouldn't have any problems with compatibility, it just says that as a disclaimer. If you do have problems, you can always re-install an older version of Java from the same site.

 

[Jollan20]

How do I know wich version is the one I need?

 

[Jollan20]

I have update 161, is that the latest one?

 

[Emoticone11]

Go to this link:

http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

Find the version which is right for your computer and make sure to get the x64 one. If you're on a mac, just download the "macOS" one (jre-8u161-macosx-x64.dmg) and then run the installer. If you're on a Windows, download the "Windows x64 Offline" one and run the installer.

Then once the new version of Java is installed:

- Wipe "Westeroscraft" from %appdata%/roaming or Library/Application Support, depending on if you have macOS or Windows,
- Redownload the launcher
