Here is the error message received this morning for this same error.
7/31/2012 2:59:06 AM ERROR: Opening output stream failed.
0x80040c07 (0x20) - :83 - .\CmdLineSearch.cpp
So from that I gather it is having problems opening the file in which it outputs the saved results. The strange thing is I have this running on two seperate computers which saves the output files locally (to the c:) and on one it works with no errors and the other I receive these errors.
Just a little background. I am running Ransack from a service I coded up so that I could run it at certain times and copy out files to a network drive when the searches are finished.
