To uninstall a previous version of System Center Capacity Planner and reinstall

  1. If your computer runs an operating system other than Windows Vista, uninstall System Center Capacity Planner by using Add or Remove Programs in Control Panel.

  2. If your computer runs Windows Vista, uninstall System Center Capacity Planner by using Programs and Features in Control Panel.

  3. If you have Microsoft .NET Framework 2.0 (Beta or RC) installed on a computer with an operating system other than Windows Vista, remove it by using Add or Remove Programs in Control Panel.

  4. If you have Microsoft .NET Framework 2.0 (Beta or RC) installed on a computer running Windows Vista, remove it by using Programs and Features in Control Panel.

  5. Install Microsoft .NET Framework 2.0.

  6. Install System Center Capacity Planner by running Setup.exe.

Technical Support for System Center Capacity Planner 2007

Free support for Capacity Planner 2007 is available on the Capacity Planner TechNet Forum (https://go.microsoft.com/fwlink/?LinkID=102145). Your feedback is important and can help improve System Center Capacity Planner.

Erroneous External Recipient in Excel Simulation Results

Exported Microsoft Excel simulation results on the Device Utilizations sheet in the Excel Summary Report and Excel Detail Report incorrectly label external recipient as ExternalEntity. The external recipient represents SMTP Internet e-mail recipients.

WORKAROUND:   None.

Running a Simulation from the Model Summary Page Does Not Show Errors

When you click Run Simulation from the Model Editor Summary page, any errors that occur during simulation are not shown until you switch to the Global Topology or Site Topology view.

WORKAROUND:   If this problem affects you, click Run simulation from the Global Topology page or Site Topology page in the Model Editor.

Standby Continuous Replication Appears Enabled For Mailbox Servers

Standby Continuous Replication (SCR) might appear as though it has been enabled for a Mailbox server when you are editing the Mailbox server role or when you pause the mouse over a Mailbox server, even though no high-availability or replication options were chosen in the Model Wizard. SCR always appears as a reference to a standby server, even when a standby server is not used in the capacity model.

WORKAROUND:   None.

Installation Error Might Occur When Installing on Windows Vista

The following error might appear when you install Capacity Planner on a computer running Windows Vista:

The installer has encountered an unexpected error installing this package. This may indicate a problem with the package. The error code is 2738.

WORKAROUND:   If you experience this problem, perform the following procedure.

To register Vbscript.dll

  1. Open a Command Prompt window with administrative privileges.

  2. Type regsvr32 vbscript.dll

  3. Close the Command Prompt window.

  4. Run Setup again.

Used Storage Space and Disk Size: Definitions of Gigabyte

In simulation results pages, Used (GB) shows the amount of used storage space in gigabytes where 1 GB = 1,073,741,824 bytes, which is the standard used by Windows operating systems. However, % Used shows the percentage of disk space used where 1 GB = 1,000,000,000 bytes, which is the standard used by disk vendors for describing the capacity of the hardware. The difference between Used (GB) and & Used is 7.3 percent.

Because of this difference in GB definition, it is possible for values under % Used to show 100 percent usage, but Used (GB) might not correspond to the full size of the storage device. In the Hardware Editor, all storage device capacities are shown where 1 GB = 1,000,000,000 bytes.

WORKAROUND:   None.

Standby Datacenter Required for Standby Cluster Replication

When adding or editing a Mailbox site on the Mailbox Sites page in the Exchange Server 2007 Model Wizard and you select Yes for Is this a standby datacenter?, you must also select at least one standby datacenter on the Application page.

WORKAROUND:   None.

Standby Continuous Replication Validation Messages Not Documented in Online Help

The following validation message is not documented in online help:

You have requested Standby Continuous Replication to <RequestedStandByDatacenters> standby datacenters, but only <AvailableStandByDatacenters> Mailbox Site(s) other than the current site were marked as being standby datacenters.

This validation message is generated in the Exchange Model Wizard when you specify that replication should occur from one site to another but not enough standby datacenter sites are available for replication to occur.

WORKAROUND:   Navigate to the Model Wizard Mailbox Sites page to create additional Mailbox sites. For each site, ensure that you click Yes for the Is this a standby datacenter? option.

The following validation message is not documented in online help:

Mailbox servers were placed at this Mailbox Site to contain the mailboxes of users in connected Client-Only Sites. If you do not wish this to happen, please return to the Networks page and specify the connectivity for Client-Only Sites so that none are connected to this Mailbox Site.

This validation message is generated in the Exchange Model Wizard when any of the following conditions occur:

  • The Mailbox Site is defined as a standby datacenter and it has no users.
  • Users at Client-Only sites are connected to the Mailbox Site that is defined as a standby datacenter.
  • There are not enough standby datacenter sites that can provide the required amount of replication.

WORKAROUND:   Navigate to the Model Wizard Networks page and specify the connectivity for Client-Only Sites so that none are connected to the Mailbox site that is set as a standby datacenter.

Effects of Exchange Server Interaction with Other Products

Capacity Planner 2007 does not model the effects of Exchange Server 2007 interaction with products other than those documented.

WORKAROUND:   None.

Additional CPU Configurations Are Available on the Exchange Model Wizard Hardware Page

CPU configurations for Hub Transport, Edge Transport, and Client Access servers are now available on the Hardware page in the Exchange Server 2007 Model Wizard. You can choose CPU configurations for those servers in the same manner that you choose CPU configurations for Mailbox servers, as is documented in online help.

CPU configurations for Hub Transport, Edge Transport, and Client Access servers are limited to 4 processor cores or fewer. CPU configurations for Mailbox servers are limited to 8 processor cores or fewer.

WORKAROUND:   None.
