Problem: "Error: Can't write to Atom Netlist File "

[Altera_Forum]

Hi all, 

i'm a newer on this forum; i've got a problem after compiling a vhdl project with Quartus II v8.1. After starting compilation, it appears this errors: " error: can't write to atom netlist file  error: can't write to file  "   Where is the problem? What have I to do to solve it?   Thanks a lot for your help.

i would think the atom netlists are written to the db or incremental_db directories within your project directory. try deleting them and compiling again 

 if that doesn't work try creating a simple project from scratch and compiling
