The OPTFINE mod error was solved successfully, For some the OPTIFINE did not work for that we had to set another version of the optfine, for those who are running the optfine normally do not recommend that update the modpack
Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.
Type in the modpack name (Naruto C Mod 1.7.10) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Naruto C Mod 1.7.10 from the list on the left. The launcher will handle everything else!
