Quartus II 13.0 SP1 fails installing

Installed plasma DE and the installer worked. Rather interesting failure mode, erroring out due to window managers.

Thank you!

Quartus II 13.1 fails terribly where Xilinx produces perfect RTL schematics from the same VHDL code! And I already upgraded Quartus to get rid of the wrong terrible bugs that showed in its RTL results. And the Intel site gives none help, no support to ask a question by sending a simple email nothing!

See next code that after days of wasted checking keeps failing in Quartus but works great as it is in Xilinx ISE 14.6!

HELP !!! QUARTUS II Web free version 13.1 (32-bit) for Windows 7 fails many times to compile a perfectly good VHDL example code!

Those examples tried never work in Quartus but the same files

WORK PERFECTLY in Xilinx ISE version 14.6 !!! (on a Windows XP laptop).

See following VHDL code below of an UpCounter that never works in Quartus II for some reason but works great in Xilinx ISE producing a decent and correct RTL schematic!

outputC: process(tempC)

begin

C <= tempC;

end process;

end structure;

I am trying to understand why Quartus makes a problem of good VHDL code where it shouldn't be!!

Any help is greatly appreciated!
