Error when connecting to BPC for Office

Question

Hi experts,
We are using BPC 7.5 MS SP06. We are in the following configuration :
Windows 7 - 64bits
.Net 4.5.2
Office 2010 - 32bits
When we launch the SAP BPC for Office (Excel) we receive the following error message :
The system cannot connect to the
(HTTP://servername) Application server. Verify that you have specified a valid
Application server name, or see if the Application server is unavailable at
this time.
Automation error
The system cannot find the file specified. (Assembly: OSoftComLibClient.dll, Object:OSoft.Consumers.Common.WebServiceCall50.WebServiceCall)
We try to register the dll by running a command
%systemroot%\SysWoW64\regsvr32 <complete path to the OSoftComLibClient.dll>
without any success.
We also tried to copy the dll from another PC but it has failed the same way.
Please, be aware that we succeed in connecting with the same user from another machine with the following configuration:
Windows 7 - 32bits
Net 4.5.2
Office 2010 - 32bits
Can you help ?
Best regards,
Anne
