This looks like you are missing the python library for Aeroo, AerooLib you can find this here: https://launchpad.net/aeroolib
After getting and un-archiving the file place it within your python path witch in your case being on windows is typically: C:\Python27\Lib, but this can change depending on how python was installed.
If you aren't seeing the areoo_reports module here are a few suggestions:
Make sure you update your modules. The easiest way to do this is hitting the "Update Modules" link on the left hand side menu of the Settings tab.
The "Apps" menu will show modules from Openerp's remote servers, if you installed the file in the addons path locally the modules will not be there, instead use the "Installed Modules" menu. From there you can see what is not installed by clicking the X next to "Installed" in the search box on the upper right hand corner.
Hope this helps, and best of luck.
