Maybe that solves your problem.  Is it the first time you try to map your design on the FPGA ?  Kind regards  GPK

thanks for your reply,  

with small designs , i don't have this problem , but when i start to compile a bigger designs this kind of Quartus II internal error come out. the full compilation pass but after 5 or 6 attempts. so a compilation of 15 minutes takes more than 1 hour. i tried to install SP2 but when i execute the install nothing happen , though i downloads the SP2 install from altera web site.

yes the error doesn't occur in every run. same problem for stratix III (in cyclone III i use only 8k of 3c120), i think it s a problem of RAM( i have 2 ram 512 and 1 1 G) or processor (Pentium D ). have you any idea of the system requirement when we target 3c120 and Quartus II 9.0

According to  

quartus ii software device support release notes (http://www.altera.com/literature/rn/rn_qts_90sp2_dev_support.pdf) the EP3C120 needs 1,5GB for 32Bit OS The Pentium D is not the problem, depending on your compile speed requirements  could you check that there is no " " space in your project directory like "c:\my Folder\"

[Altera_Forum]

there is no space in the project directory. 

my ram config meet , i don't know where the problem.

In the past I had a similar problem and it turns out that the memory of the PC was the problem.  Kind regards  GPK
