ExecuteOutOfProcess calling a transactional child package causes Access is Denied.

I have a master package that contains an Execute Package Task whose ExecuteOutOfProcess flag is True, and that calls a child package whose TransactionOption = Required. The job is running in Sql Agent, and the step that calls the master package is configured to run under a certain domain account that is not in the local Administrators group. With this, I get the following:

messageText: Error 0x80070005 while loading package file "C:\program files\microsoft sql server\90\dts\Packages\ETL\Fact_Various_TransactionalChannels.dtsx". Access is denied.

When I add the domain account to the local Administrators group, this error does not occur. From a blog entry, I read that when a child package is executed out of process, the resultant OS process is called dtshost.exe (http://blogs.conchango.com/jamiethomson/comments/1414.aspx). Do I simply need to give my domain account permission to spawn this process? If so, what permission is it? Is there a group that contains this permission?

Is it possible that the domain account does not have access to "C:\program files\microsoft sql server\90\dts\Packages\ETL\"

|||Unfortunately, no. The account has full control over that path.
