Hi, I am trying to use cygwin on my office laptop, which as a software called powerbroker that provide admin privileges for installation of third party software like cygwin. Powerbroker has worked well with all other software installations, however cygwin is not installing correctly with powerbroker. I know for a fact that the issue is because cygwin is not compatible with powerbroker (or vice-versa), as when I uninstall powerbroker and install cygwin using setup-x86.exe --no-admin, it works just fine. However, when I re-install powerbroker and try to open cygwin I get cannot fork error. I tried to rebase, but that did not work either. I need powerbroker to manage other programs and so cannot get rid of it. Any help would be greatly appreciated!! The setup error occurs right at the end of the installation process as shown below. I have also attached the full setup log. 2017/04/04 11:52:56 Changing gid back to original Visited: 75 nodes out of 9639 while creating dependency order.
