Just tried the rc2 MSI on Windows 7 x64. Go through the normal setup I always pick the Advanced option of compiling the .py files. In rc1 the script it spawns works as it should, with rc2 I see it pop up, have a Traceback before it quickly closes again.

And this fails the install.

This is, by the way, an upgrade install over rc1. Need to test a clean install at some point as well.

Running the MSI with /L* gives me:

Action 8:13:22: RemovePip. 
Action start 8:13:22: RemovePip.
CustomAction RemovePip returned actual error code 1 (note this may not be 100% accurate if translation happened inside sandbox)
Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor.  Action RemovePip, location: F:\Python34\python.exe, command: -m ensurepip._uninstall

Ah, this might be something we need to fix in the process of the installer. If you have a pip installed that got updated, the install will now fail due version mismatch. Updated the title.

Attached patch uses a similar solution to the one I used in issue 19744 to better handle "make install" and "make altinstall" when SSL/TLS are missing: it converts the version mismatch to a printed warning that still reports "success" to the caller.

Nick, this resolves the installation issues for me at least. +1
