First off, I'm a total noob with forge, so please forgive me if I'm totally doing this wrong..

 

After the recent update I cleared all my old mods, as I decided I needed a change..  I downloaded the latest version of Forge universal.  Then after  reinstalling Minecraft (first copied out my texture packs and save files to a safe location).. I opened minecraft.jar and deleted meta-inf ..  I then copied over all the files in the forge universal file..  and started up minecraft...  it started to load then popped up with a small window saying " FML is setting up your minecraft environment"  I assume this is the forge set up...  however it has been at 0% for about an hour.  I have closed and tried several times with no success.  Am I doing something wrong? Please advise.

ForgeModLoader-client-0.log?

There is no log, that I can find..  Minecraft won't successfully load..

I getting the same error, forge wouldn't install it just crashes my server, so then because it doesn't install I have no forge log file.

There is ALWAYS a log be it in a file or in the console GET IT

I'm not 100% sure, but I think the problem might be the recent patch. I have tried to install a couple other of my old mods that I used before the patch and they do not seem to work.. Perhaps the changes made in the last patch, were just enough to prevent some or most mods from installing... Just a guess.

Read the EAQ ...

For Windows users, use this batch file to get a crash log:

Mac/Linux users can simply run your Minecraft launcher from terminal:

java -cp minecraft.jar net.minecraft.LauncherFrame

This is all the server console says then crashes, and I get this error over and over again in the console.

 

 

Your server stopped unexpectedly around this time. If you told it to exit in-game, this is nothing to worry about; otherwise, the last 10,000 bytes of output from the server, given below, may provide you with clues on what went wrong.

Seems yu're installing Forge on a minecraft jar that isn't the same version you're targeting.

If you download 1.5.2 Forge you MUST put it in 1.5.2 minecraft.

How does one check the version of a minecraft jar on the server
