I recently created a modpack with a hidden link. As of March 2017, dropbox does not allow the creation of public folders with a free account. As a result, I cannot download my modpack in the launcher. However, after a failed download, the technic launcher creates a directory for the modpack - in which i can unzip the file downloaded manually using the dropbox link. After i do this and go into the lancher, I cannot press play and start playing the mod, the button still says install. I guess what I am asking is - Is there any way to manually install a modpack?
