Cannot open Query/Workbook with Analyzer on my PC

Hi,

I can't open queries or workbook on my computer. When I click on the icon "open", nothing happens !!!!!

1st - I don't understand why the icon description is in german : "Offnen"???

2nd - here is my configuration: windows 7, Excel 2007 (student pack) and SAP BW 710

I can execute Query Designer, Crystal Report... ... My only problem concerns the Analyzer.

Could you please help me?

FYI, I installed the note 1121263 (= the zip file "lockbackRegKey.msi" on my PC)
