[03:56:15] [main/ERROR] [LaunchWrapper]: Unable to launch
Rather than using Java 7, which can't even be downloaded without an Oracle account (which will ask for a business contact and all) and is a major security risk (even the launcher uses an outdated JRE but at least it is only accessible by Minecraft, which can be trusted), try the following patch:
From here you need to find your way into your libraries directory for Forge. On Windows, the direct route would be:
For 1.7.2: %appdata%\.minecraft\libraries\net\minecraftforge\forge\1.7.2-10.12.2.1147 (or switch 1147 for the version you're using)
You can make a backup of the JAR if you want at this point. But now open up the JAR in WinRAR or what ever program you use for such things. First, go ahead and delete the META-INF directory in the root of the JAR, or you'll get a crash related to security, just like in the old JAR-modding days. Now navigate your way through cpw/mods/fml/relauncher. You should see a CoreModManager.class in here. Just drop this patched version on top, and you should be good to go!
Also, always run separate versions in separate game directories; 1.7.x will crash if the render distance was set to above 16 and otherwise you'll have to at least reset settings every time you switch versions, then you risk corrupting worlds by opening them in the wrong version, plus separate directories allows you to run separate modded instances as each directory will have its own mods folder:
If the player wants to change the location of the Minecraft directory, they can turn on the "Game directory" option. Navigate to the folder where the player wishes the game files to be placed. The player can also open the chosen directory by clicking the green arrow-shaped "Go to folder" button.
The link works for me; just in case, I re-uploaded the file to Dropbox (note that the forums will warn you about an external link but you can click on continue. Also, your AV/firewall might have issues with the file but it should be safe):
According to the thread it should work for both 1121 and 1147, and probably many other 1.7 versions (these are the recommended and latest versions), you only need to change the path (go to "%appdata%\.minecraft\libraries\net\minecraftforge\forge\" and look for the corresponding version):
when i launch it the window never shows up

Start 1.7.2 without any mods/forge once
Then reinstall forge 1.7.2
Make sure your mods-folder is empty
I've heard it might have something to do with it not being a correct version of Java.
Try launching it with Java 7, see if that works.
