HELP ! Can't Find C2H in Quatus 10.0SP1 Eclipse !!!!

thanks alot for your help, I begin to see a big sh..... there are 2 softwares NIOSII 10.0 IDE environnement for soft and SBT ECLIPSE and each soft has advantage and problems. In the first one ther is not NIOS MENU to rebuilt the BSP (or edit it). In the SBT tool, at my opinion, it's the best tool for programming, the problem is that it's impossible to use C2H because not visible !!!! What happened ? 2 tools to use the same project ? Its impossible to manage ! I hope ALTERA will correct this mistake. At now, It's impossible for me to teach FPGA and IP processors based on ALTERA messy Tools !!!! If some one have methodology to use One tools to design software and to use C2H, Thank's in Advance. Regard's
