Unable to add storage system in ESI

Hi,

I have installed ESI in Windows 2012 R2 server and i am facing issues while adding the storage system of VNX-Block system type.

After providing the username,password,SPA's IP address,SPB's IP address and 443 port number,the Test connection fails with the following error "Unable to load DLL 'EMC_PEGASUS_CLARIION_ADAPTER.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007". However i can find the same .dll file in the VNX.Adapters PlugIns Folder which was created during ESI installation.I have also captured a screen shot for reference..

! !@

Any help would be appreciated..

Thanks,

Bhuv.
