I am trying to find .msi or .exe installation files for PHP Manager 1.2 (x64). I found the x32 version, but cannot install it on x64 OS.
Almost every link for PHP Manager points to
http://phpmanager.codeplex.com/releases/
but all traffic will be here
https://archive.codeplex.com/?p=phpmanager
If anyone has any ideas please let me know!
