Setup would not have done any of these things for you. However, Cygwin tar won't work because it will load the DLL that you're trying to update, and a non-Cygwin program like WinZip will put everything in the wrong place. The solution is to use setup.exe . You should be given the option to install it. You may have to restart Windows to clear the DLL from memory.
Snapshots are risky.
They have not been tested. Use them only if there is a feature or bugfix that you need to try. You may have to hunt for one that has a copy of the latest snapshot. Go to the first , previous , next , last section, table of contents .
