Honored ContributorHello,
I have been having the same problem on Ubuntu14. I must use quartus version <= 11.1 since I need support for my device Max 7000 family...it is very annoying that this libpng12.so.0 (that is shipped with the installer) keeps preventing installing the program...even if I change the LD_LIBRARY_PATH to first have the /usr/lib (or whatever) in the list the installer still keeps picking up the libpng12.so.0 sitting in the installer's directory. Also, if I replace it with a symbolic link to point to the system libpng12.so.0 (sitting in /usr/lib/) then the installer says that I don't have a valid installation source... Actually a similar problem occurs when I try to start a browser in the Help menu, then I get an error saying something is wrong with the shipped libstdc++6.so.0, but at least replacing that with a symbolic link pointing to the system one under /usr/lib solved the issue.. Some fix would highly appreciated... Balint
