Daa-meganizer not found

Dear MEGAN users.
I installed MEGAN 6.12.3 version by conda install -c bioconda megan. When I run MEGAN, it worked and it showed the interactive graph. But when I run daa-meganizer or any commands in tools directory, it showed file or directory not found although they are there. I also tried to run daa-meganizer -h and it showed /home/te73huq/miniconda2/jre/bin/java: File or directory not found.
Have you ever come across this problem?
2. I tried to meganize the daa file using the interactive graph. It takes time. I wonder how I can export the meganized results (taxonomy, functional assignment). So, next time I don’t need to meganize the daa file again.
Thank you in advance and I would appreciate your help.
Best,
Qianqian
