Hi..

The problem is due to the protection level property of the package. Figure what is the property value.

The config file has to be designed based on the property you have used.

2. if the package was designed using "encrypt password with user key" type of protection level then the credentials with which the package is being executed are not having rights to access them.

By changing the Protection Level property and config file u can overcome ur error.

cheers
