BPC 10.0 MS Admin client not opening

Hi gurus,

We are using SAP BPC 10.0.16.0 and after I installed the BPC admin client on a few of the users, I am getting two different errors. On one user it is not opening at all. On the other user it is showing

On one other user it is showing

"exception error has occurred; check the client log file, log ID"

after I open the admin client.

on checking the client log file I saw this

DetailMsg  : {GetLateBindedObj: Value cannot be null.

Parameter name: type(Assembly: OSoftWebFolder.dll, Object: OSoft.Consumers.Common.FileAccess50.CommonFileAccess)(Assembly: OSoftWebFolder.dll, Object: OSoft.Consumers.Common.FileAccess50.CommonFileAccess)}

What could be the reason for this?

Regards,

David
