Hi @MohanMuniyappan ,

You can try adding the path as a trusted directory.

sadmin trusted add C:\Windows\syswow64\

Run the application and verify if it works.

Thanks

Can you give us the full error message in the log? 

THIS IS CRITICAL!!!!!!! 

sadmin trusted add C:\Windows\syswow64\  - You just cause a big security hole in your environment. Please remove this and let us know the error.
