troubles with Nios2 ide and Windows7

[Altera_Forum]

I have troubles with Nios2 ide and Windows7 

  I have a new PC with AMD A6-360 (4xCPU), 2,6GHz, 4GB RAM and Windows7 (32).  I have bandied from XP to Win7. If I compile the Nios SW project with “nios2-ide.exe” under XP it is OK. If I compile under Win7 the Nios SW project with “nios2-ide.exe” or with “eclipse-nios2.exe”. I get the error messages.    D:\_Prg\PrgEPLD\Altera\DesignSuite110web\quartus\bin\cygwin\bin\sh.exe: *** fatal error - couldn't allocate heap, Win32 error 487, base 0x6C0000, top 0x6D0000, reserve_size 61440, allocsize 65536, page_const 4096  1 [main] sh 3144 fork: child -1 - died waiting for longjmp before initialization, retry 0, exit code 0x100, errno 11    D:\_Prg\PrgEPLD\Altera\DesignSuite101web\quartus\bin\cygwin\bin\make.exe: *** fatal error - couldn't allocate heap, Win32 error 487, base 0x9E0000, top 0xAD0000, reserve_size 978944, allocsize 983040, page_const 4096  2 [main] make 4980 fork: child -1 - died waiting for longjmp before initialization, retry 0, exit code 0x100, errno 11    I get this error under Quartus/Nios2-ide versions 9.1 Subscription, 10.1 web and 11.0 web.  I have started my PC with minimal driver and services (msconfig -> diagnose).  I have made a DW in /HKLM/Software/Cygnus Solutions/Cygwin/heap_chunk_in_mb 1024.  I started the IDE in XP compatibility modes and as administrator.  The problem is ever the same.    What is the problem?    Thank You!
