The easy way

1. Download and install nsis-2.46.5-Unicode-setup.exe from https://code.google.com/p/unsis/.

2. Download: https://github.com/bliker/cmder/releases/download/v1.1.3/cmder.zip

3. Select: "Installer based on ZIP file"
   

4. Set meaningful default extraction path:
   

5. (optional) Sign the resulting installer.

   Follow guide: http://blog.assarbad.net/20110513/startssl-code-signing-certificate/

   Then sign using:
   signtool.exe sign /v /f cert.pfx /ph /t http://timestamp.verisign.com/scripts/timstamp.dll cmder-setup.exe

#### Expected result

Something similar to cmder-setup.exe from https://github.com/iljau/cmder/releases/tag/v1.1.3-installer

As much as a portable version is cool to have, I would prefer to have an installer also - that creates start menu shortcuts, registers the context menu extension (if the user chooses so) and also uninstalls everything again. It can't be that hard to wrap up a little .msi?
