Hi there, so I've been playing FTB since the Launcher came out, and I have a problem. Yesterday I tried to open the launcher... and nothing happened. I tried over and over again, doing everything I knew how to do, and nothing. So I said "Okay" backed up my save files, and deleted all my FTB stuff. Then today I redownloaded it. Again, I tried to open the launcher, and nothing. The thing that asks me if I want to run the file pops up, I hit yes, and then... nothing. Nothing happens.

Any idea what is going on?

Needs more cowb- I mean log entries. Use this format:
FTB Launcher version (if this isn't the newest update update and try again):​
Minecraft Version:​
Java version:​
Detailed description of the issue / how can the issue be recreated:​
Error logs:​

Do you download the launcher (save as) or do you use run?
incase of run, use save as and save it either on your desktop (in a folder if you want) or on a different folder on your C or D drive.

Most of the times when the laucher is acting up it because it's in a invalid path (aka .roaming etc)

Since you said you already backed up your saves....
If you remember where you downloaded your Feed the Beast to, delete all of the files from there that you downloaded. Also go into your Roaming folder (you can get there by typing %appdata% into the search bar of your Start menu) and delete all of the FTB downloads from there as well. Check your Downloads folder or other Temp Internet Files folders for any other downloads. Empty your recycle bin

Restart your computer (just to make sure everything got completely deleted.

Make a folder on your desktop, and name it FTB

When you re-install from the website, make sure none of your anti-virus/firewalls/popup blockers are blocking the download. Put the download in the folder you created.
It should launch without a hitch

@dememtia
I'm using the latest version of everything, I already explained my error, and I can't get an error log out of anything because the launcher won't boot. Period.

@Nessiroj
I'm on Chrome, I also tried Firefox and Internet Explorer. All download and save the same file. Still nothing.

@Ashzification
Tried it, still nothing booting. If it helps, Minecraft is doing the same thing.

Backup your worlds then delete your .minecraft folder and your .ftblauncher folders? What version of java do you have? What version of windows? Are you certain you only have one version of java installed? What version of the launcher are you using jar or exe?
