Google App Engine ImportError

Question

I've come to run my app in development locally this morning, in the Google App Engine Launcher for Windows. Up until yesterday this has been working fine, and the code hasn't been changed since then.

Now, when I try to run the app on localhost I get the yellow warning sign in the Launcher and the log shows the following;

2012-08-02 08:37:54 Running command: "['C:\\Python27\\pythonw.exe', 'C:\\Program Files\\Google\\google_appengine\\dev_appserver.py', '--admin_console_server=', '--port=8080', 'C:\\Documents and Settings\\preston\\My Documents\\Google Drive\\Development\\Instance']"

ImportError: Module use of python26.dll conflicts with this version of Python.

I've only ever had Python 2.7 installed on this machine, nothing has ever attempted to use python26.dll before as far as I know...

Also, I've checked the Launcher for updates, nothing found. Has anybody experienced this before? The most baffling thing to me is that it's changed behaviour since yesterday...

Answer 1

Solved: As per commenter's hints, I tried closing all applications running which had been installed since the last successful run. This amounted to only one; Google Drive. Stopping that process allows the App Engine Launcher to run the app just fine, so the conflict's coming from two Google apps!

Thanks for the help.
