I get this error when trying to import psycopg2.. I've searched for days, and found no solutions. I've tried installing the Visual C++ 2008 Package, but I still get the same error.

According to this thread you need to install an earlier version since there were problems with the latest build.

Simply install an earlier version, (2.0.10 works great), even with PostgreSQL 8.4.x series.

On Windows, make sure your path includes the Postgres bin directory. In my machine it's c:\Programs\PostgreSQL\9.3\bin.

You can also try installing win-psycopg from here
