I've created a workflow for a Sharepoint 2010 Enterprise Infopath FOrms library. Even with the default initiation form, a user with full control permissions on the library gets the following error when trying to manually start the workflow:
A form template (.xsn) file cannot be accessed. You may not have the required permissions to open the file.
I can start the workflow with no problem with my site collection admin accounts.
What can I do?
