Unable to unzip any downloaded modpack through platform URL


Question

Posted

Launcher Version: 253

Operating System: Windows 8 (x86) version 6.2

Java Version: 1.7.0_25

Antivirus Program: Windows Defender

Description of Problem:

So I wanted to download a mod-pack such as Infamy or Zeppelin, so I copied the platform URL on to the launcher. I can see the mod-pack, seems fine and I proceed clicking the launch, then this strange error came in:"Error unzipping the following file".

Then I tried downloading another mod-pack, using the same steps, A familiar message came up, I tried using variety of mod-packs and guess what? Same error! Well hope you can catch my drift because I do want to try a mod-pack made by the community.

Also, I checked the console and these logs followed along with the error. They're not from the logs folder by the way.

Error Messages:

Error unzipping the following file

Please consult the modpack author, or try running the pack again

Error Log:
