Hi All, I'm running Cygwin (CYGWIN_NT-6.1-WOW64 1.7.5(0.225/5/3) 2010-04-12 19:07 i686) under Windows 7 x64 professional. I have had an issue using run.exe to start programs for Cygwin-X. In my .startxwinrc file I have this command: run urxvt -g 100x40 -e /bin/bash --login When I start up the X-server using the default shortcut (C:\cygwin\bin\run.exe /usr/bin/bash.exe -l -c /usr/bin/startxwin.exe) I receive an error message like this: Error: could not start C:\cygwin\etc\alternatives\urxvt j-g 100x40 -e /bin/bash --login The characters between 'urxvt' and '-g' change each time. If I change the command so that run.exe is not used it works fine. Maybe there is some memory issue with run.exe on 64-bit systems? Anyway I just thought I would bring it up. Attached is the output of 'cygcheck -s -v -r' which may or may not be useful. When running this command the following was printed to stderr: /usr/bin/cygrunsrv: warning: OpenService failed for 'DcomLaunch': Win32 error 5 Access is denied. /usr/bin/cygrunsrv: warning: OpenService failed for 'odserv': Win32 error 5 Access is denied. /usr/bin/cygrunsrv: warning: OpenService failed for 'ose': Win32 error 5 Access is denied. /usr/bin/cygrunsrv: warning: OpenService failed for 'pla': Win32 error 5 Access is denied. /usr/bin/cygrunsrv: warning: OpenService failed for 'QWAVE': Win32 error 5 Access is denied. /usr/bin/cygrunsrv: warning: OpenService failed for 'RpcEptMapper': Win32 error 5 Access is denied. /usr/bin/cygrunsrv: warning: OpenService failed for 'RpcSs': Win32 error 5 Access is denied. -- ------------------------- Daniel R.
