Hi,
we tried to Update a manged solution in CRM 2011 RTM with a newer version. The Import fails with the message
A managed solution cannot overwrite the AttributeMap component with Id=0765e87f-cd53-e011-bb82-00155d397001 which has an unmanaged base instance. The most likely scenario for this error is that an unmanaged solution has installed a new unmanaged AttributeMap component on the target system, and now a managed solution from the same publisher is trying to install that same AttributeMap component as managed. This will cause an invalid layering of solutions on the target system and is not allowed.
The only unmanged customization in the target system are two Workflows/Processes where the Queue-Lookups have been adjusted to the system.
A similar issue was reported in
http://social.microsoft.com/Forums/en-US/crm2011beta/thread/4d92c7a4-9a1f-47cd-9896-2268b927c9bf
It implies there might be a bug. Is there a workaround? When can we expect the issue to be fixed.
Thanks in advance for any help.
