Hello Amit, I have checked it again with a plain new installation with openerp-allinone-setup-6.2dev-latest.exe on my Windows 7 machine with the following the results: IE 9 --> HTTP 404 error; I can't login! This is also the case with the configuration in my first bug report. Firefox 16 --> can login but again error with the already listed traceback when i go to modules and click on the module name to show the module details view. Thanks 2012/11/19 Amit Bhavsar (Open ERP)
