Can I refresh installer in order to get new system settings?
Hello,
such problem appeared:
I have to uninstall Cygwin, and install PostgreSQL. I do uninstall step by step as it is described in documentation - stop and remove all services, remove directories and registry,unmount all information related to Cygwin(umount -A, remove the "C:\cygwin\bin" from the systme PATH.
If I don't remove the "C:\cygwin\bin", usually an error appears on starting PostgreSQL installer, but I am sure it is not in PATH anymore.
Then I run the PostgreSQL installer and the error still appears. So I think the installer still remember system settings from the moment it has been started, and it knows that "C:\cygwin\bin" is in PATH.
I tried to split the installer in two parts, one for Cygwin uninstalling and one that starts after that with PostgreSQL installation, but it is the same.
So, is there way to refresh installer, or restart it again(without rstarting windows), or some other way?
Thanks.

You remove it from the path but Windows isn't changing the PATH variable. If you type: echo %PATH% from a DOS prompt you'll notice that Windows still has "c:\cygwin\bin" in it's path. So, you'll need to set the path again using set with all the other paths except the one you don't want. Type: set /? from a prompt to see the options. I've never had to do this so I'm just assuming. I removed a path from my path using the GUI and it didn't reset the PATH variable either until I restarted but SET will also do that.

No, there isn't.
Hi, thanks for the reply :)
I checked PATH, after removing directory from My Computer -> Properties ->Advanced -> Environment Variables, with "echo %PATH%" and "SET" commands. In both cases my directory was missing. But when I tried to change PATH with SET command, no, changes appears.
Thanks anyway, i will read about this more, when I have little time, guess,I can find a solution :).
