We believe we may have the 1.6 installation for texturepacks working on the launcher. Currently DW20, FTBLite2 , Horizons and Magic World 2 are available in Soartex. Please do not tell the Soartex guys if there's a bug right now, this is a test phase and we are not 100% sure it works yet. For now this is just a test to see if the code works and installs the texturepacks to the correct location. Once it definitely working we'll get updated versions from the Soartex crew for any pack they wish to cover.
