Problem in creating Asymmetric keys

I am a novice to the SQL server. I am trying to create Asymmetric key using the query

CREATE ASYMMETRIC KEY PacificSales19 AUTHORIZATION dbo

FROM FILE = ' C:\temp\temp1.snk'

ENCRYPTION BY PASSWORD = 'ABC123!@.#$';

GO

But I alwys get the follwing error

The certificate, asymmetric key, or private key file does not exist or has invalid format.

Can anyone please guide me as to how to go ablout creating the ASYMMETRIC KEY FROM FILE.

Thanks and regards

The statement you are trying is correct - this is how you can create an asymmetric key from a file.

You should check that the specified path is correct and that the file is not corrupted. How did you generate that file?
