I downloaded Python and installed it, and when I go download GoogleAppEngine_1.2.0.msi and try to install it and I get this error:
This installation package could not be
opened. Contact the application
vendor to verify that this is a valid
Windows Installer package.
Am I forgetting something? I am assuming this is pretty simple.
I had the same error. The file downloaded by IE was about 190k and would not run. The file ought to be 2.7M. Firefox downloads correctly. Also IE will download correctly if you select RUN instead of SAVE. That is my experience and I now have the SDK installed. I hope this helps you.
