Update your firewall and antivirus software. As stated, using a firewall shouldn’t mean that League of Legends won’t launch. However, if you’re using outdated definitions, they might not recognise your LoL client.

Remote Desktop is giving an error upon launch:

The remote Desktop client software on this computer does not match the administrator software version. The Remote Desktop administrator software requires a newer version of the client software. Click 'Check for Updates' to search for updated software.

I've reinstalled Remote Desktop from the App Store multiple times and am running the latest version of OSX (10.8.4).I recently installed the preview of 10.9 but downgraded back to 10.8.4 by doing a migration assistant on a 10.9 time machine backup. This may be the culprit, but I wouldn't know how to fix this problem I'm having.

Installed 3.6.2: http://support.apple.com/kb/dl1594 manually which isn't available on the App Store (where I usually downloaded it from), and it works now.

It tells me I'm updated and everything but when I launch the client it simply opens the console and it stays blank

commented Jul 5, 2015

For me it says 'Could not find or load main class mage.client.MageFrame' in client console and 'Could not find or load main class mage.server.Main' in server console
Already forced update, no improvement.

commented Jul 5, 2015

What os and os version is used?
I found this:
http://www.slightlymagic.net/forum/viewtopic.php?f=70&t=16358&p=169586&hilit=mage.client.MageFrame#p169579
Delete the 'installed.properties' file in the directory of the XMage launcher.
Then all should be again downloaded and installed.

My Mac Won T Update

Tried that, doesn't work for me, same problem persists

commented Jul 5, 2015

Also there is nothing in my xmage folder, if that helps

My Mac Won't Update Software

commented Jul 5, 2015

Operating system?
Some mac OS users had problems in the past. There is a XMage home
http://xmage.de/xmage_mac
that you can set in the launcher settings.
That uses still an old launcher version that seemed to work on macs.

Mac Won't Update Os

Using Windows 7 64 bit so OS probably isn't a problem. Anyone know of any links to old versions of the launcher?

commented Jul 5, 2015

You can set the xmage home in the launcher to:
http://xmage.de/xmagelauncher31
to get the old launcher and the current xmage release.

commented Jul 6, 2015

Yep, still does the exact same thing for me

commented Jul 6, 2015

I can imagine 2 possible reasons now:

  1. Windows Firewall blocking (check in the setting of windows firewall that 'Java(TM) Platform SE binary' is allowed to cross the firewall).
  2. Problem with the file path you located the launcher.jar. Maybe it can help to use another directory, best with no blanks or special chars in the complete path.

The firewall is what it was. Thank you very much!

commented Jul 6, 2015

I can confirm that after updating to 1.4.2.v1 everything works fine again. Launcher 'updated' itself to v0.3.1.
Thanks for the effort.

You're using a mac?
And the default launcher did not work?

commented Aug 9, 2015

Using Windows 8.1 (64 bit).
Initially when running client nothing happened, checking logs:

I created 'mage-client' folder inside xmage folder, but now the error is: 'Error: Could not find or load main class mage.client.MageFrame'.

Now I suppose maybe is something related to Java, doing java -version in console I get:

as this program requires other version maybe is something there...

I don't know, some help is appreciated.

commented Aug 9, 2015

There was also for some people a problem with the launcher 34.
Please try if it helps to use the old launcher 31.

To test this you can switch the xmage home in the launcher settings to
http://xmage.de/xmagelauncher31
update the launcher and reinstall java with the launcher if needed.

commented Aug 9, 2015

I don't know if I did what is need, if you can be my explicit.

Exactly what I did:

  • download launcher from http://xmage.de/xmage/XMageLauncher-0.3.1.jar
  • edited from installed.properties part:

complete file after install:

Now log file is:

and yes, still nothing works,

commented Feb 28, 2017

I'll close this issue because it seems to be outdated but feel free to create a new one if this problem still exists.

commented Jan 12, 2018

Specify this for the Mage Client Main Class:
mage.client.MageFrame
Sometimes, it doesn't automatically find it.
