I am having the same problem. I am on a Dell netbook 64bit Windows 7 2Gb RAM and when ever I click the Technic Launcher all i see is Checcking Launcher Version then it dissapears and then nothing. I have even tried opening it with Java using the .jar file and still no go. What could be the problem as both my other laptops run it fine but this one is not. I have java jre7u6 x64 version so I can't see it being my java that is the problem.
Any help would be highly apreciated and I hope I'm just being a derp.
