Updating Access Tables Using the Runtime Version

[normanpm]

I'm converting most of my databases to be used as runtime versions, as most utilize SQL Server tables. One database though uses access tables throughout. When i create my forms to update the data for these access tables though, most of my runtime users cannot add any new records to the access tables. When i replicate the tables to SQL server and ODBC access them, they can. These users never previously had full MS Access installed.

Is there some type of security flags that need to be set on these tables to allow for appends through runtime? Are these users missing some executables?

Thanks
