IDT- Connection Edit Issue

Hello Experts,

I am using BOE 4.2 SP7 version.

In IDT, while trying to edit the connection I am getting the following error. Any help is appreciated.
Error:

DBDriver failed to load : C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\dataAccess\connectionServer\drivers\lib32\dbd_oci.dll (The specified module could not be found.
)
