Enesys RS Data Extension 3.5.26 fixes the following bugs:

• Forms Based Authentication: in some cases, the license type would not be properly detected and Form Based Authentication features would not be activated.
• Object model would be falsely detected in some cases (as a workaround it was possible to force Object Model to false).
• The Query Designer would not display the toolbar properly when using BIDS 2008 R2 with French language.

You can get the new version on the download page.
