I am using the command
package.Encryption.Password = "abc45th";
To add a password prior to saving my spreadsheet. All works fine when saving from my local PC to a network location. When I deploy my web app to my 64 bit server using the command to an the encryption password causes the save command to fail. If I comment out the encryption line all works OK, so I do not think it is a permissions issue.
Anyone come accross this one?
