I have a master package with a sequence container inside it. Inside the container are three execute package tasks. All the packages including the master are set to DontSaveSensitive, except for one which is set to encryptwithpassword. When I execute the master, the first two packages are executed, but the last one fails. The master package has this message: Error: Error 0xC0012050 while loading package file " ". Package failed validation from the ExecutePackage task. The package cannot run. . and the package which fails has this message: Error: There were errors during task validation. Any ideas what can cause this?

Sounds like a basic validation failure. In other words, the package does not even start to run; SSIS is still validating the package against the database. Open the package in BIDS and point it to the database that is uses when running from the Master package. See if presents any validation messages.

re-execute by setting the property DelayValidation = TRUE for the master package The error does not say it has anything to do with protection level

Normally the master package shouldn't have the same protection level, as you can specify the password for the child package inside the Execute Package Task. As no_prakash and Randy said, there is probably some other validation error going on.MCTS, MCITP - Please mark posts as answered where appropriate.

In this case we couldnt get the master to complete unless all the packages inside the master were set to encrypted w password as the protection level. thanks for all your ideas.
