you have the manual download set for the dropbox link, not the direct download.
to set it to a direct download, right click on the pack's zip and click on "copy link" and then set that as the modpack location.
how about instead of making a low effort post you try to give us any info about:
Technic launcher version.
OS and OS version.
Java version.
What modpack. (if it is any that is NOT by the Technic team, go bitch at the modpack maker NOT the Technic guys)
And how about you use the fucking search function as this is a commonly fixed error.
When I said "Download for the Technic launcher" I was trying to make it clear I was speaking about your modpack on the Technic platform website.
(EDIT)
2 errors with the pack:
1. you pulled all of the mods from Tekkit witch is 1.5.2 and your pack is 1.6.4.
2. you named the zip file "XEliteVersion1.zip.zip" and the modpack.jar "modpack.jar.jar".
it HAS to be "modpack.jar"
please send us the download for the Technic launcher and the download for your modpack on what ever file hosting website you use.
if you do that, we can help.
with the amount of mods in the pack, it would make sense if it was an ID conflict.
but if that was the case, NEI would have forced a game crash and tell you what IDs are conflicting.d
in your modpack.jar you put everything in side a folder named "Modpack".
put everything inside that folder in the "Modpack.jar" main, it will work then.
also, it is agnest the rules to Sign your post
We won't be able to see what is really happening without 2 things:
1. you don't have the console open, so we can't see what is happening in the back ground.
2. you didn't link the pack, so we can poke though it to see if its a set-up error.
the website for Technic was down earler, so that may be the only error.
try it again, if it still happens, try posting a bug report on the modpack's bug forum.
