When importing a management pack in System Center Operations Manager 2007 that has a dependency on another management pack, the import may fail with the following message:
<ManagementPackName> could not be imported. If any management packs in the Import list are dependent on this management pack, the installation of the dependent management packs will fail. The requested management pack was invalid. See inner exception for details. Parameter name: managementPack
This issue occurs because a management pack that the management pack being imported depends on isn't imported in the management group. In order to work around this problem, import the dependent management packs first then import the management packs that depend on them.
NOTE If you're unsure of the dependencies for a management pack, they will be listed in the management pack guide.
