Launcher - Flashes then disappears/ JAR - Command box flashes then disappears

[nrm123]

Launcher Version: Latest

Operating System: WIndows 7 Home Premium 64 bit

Java Version: 7u5 64bit

Antivirus Program: Norton 2011/2012 (tried it with no AV still didnt work)

Description of Problem:

Ive tried all of the fixes seen in other threads, ive checked the fixes in the official page and none work. Before anyone says its my AV its not. i tried it with no AV installed and it didnt work, ive tried it on my dads laptop with exact same AV and it worked. Ive tried the launcher it flashes and disappears, Ive tried running the JAR file i get a flash of a command box and then nothing. Ive tried many different times and i was getting banner freezes but now i dont even get that. I have tried the BAT fix doesnt work. In .technicpack all that is there is the JAR file no logs nothing.

Seriously need sorting this!

We'll need the exact contents of the batch file, and where it's located then, please.

i did try the BAT file with the mk line as well dont work either i assume its something to do with the path ?

Try putting the batch file in the same directory as your launcher .jar and changing the whole c:\Users\Packard Bell... path to just the name of the .jar, like so:

"C:\program files\java\jre7\bin\java.exe" -Xmx1G -jar technic-launcher.jar

pause

it doesnt work, i will try on weekend when i remove AV again but i dont think it will work. Ive allowed it through Windows Firewall and Norton...

just edited the logs because they have changed...looks like the logs are loading the launcher form? but it is not showing.

[nrm123]

just a thought, is there a way of editing the code in the JAR file to bypass the banner and straight to the launcher?

[nrm123]

still no good

It is at this point that would make sure you have the newest launcher by completely removing it and downloading a new copy. I have had numerous problems myself when I tried to change launcher versions (even non-version-number-change versions) without deleting old files.

just downloaded newest launcher still no luck with same logs dont think i am meant to play technic :|
