To ensure the template is indeed unique you must update the name field shown from your template below in red to something unique.
</ComponentTemplates> <DeletedComponentTemplates /> <Id>425</Id> <Name>Copy of GOLDEN-TEMPLATE-Q-SQL Server 2005-2008 Performance (SQL)</Name> <IsMockTemplate>false</IsMockTemplate>
Secondly, you will need to update the UniqueID field to something unique to your environment. Without updating these two fields a collision will occur with the original template, causing the errors you are seeing.
<ModuleVersion xmlns:d="http://schemas.datacontract.org/2004/07/System"> <d:_Build>0</d:_Build> <d:_Major>6</d:_Major> <d:_Minor>1</d:_Minor> <d:_Revision>1835</d:_Revision> </ModuleVersion> <UniqueId>c5ef396f-977a-451d-8297-af2387b8d664</UniqueId> </ApplicationTemplate></ArrayOfApplicationTemplate>
Alternatively, I would strongly recommend looking at using SAM's AppInsight for SQL instead of this template since it does not require any of these manual changes.
