cannot get Osoft virtual directory object: (SAP BPC 7.5 sp08 issue)

Hi SDNer

I am facing a different issue after installing sap BPC 7.5 sp08. i ran server diagnostics when i login with a domain user (domain name\bpc_sysadmin) and i see error message as :

cannot get Osoft virtual directory object: Automation error the system sould bot find path specified- incorrect

but when i run the diagnostics after logging in with local user Administratot- all green and its ok.

can some one through views...

regards
