Update Rollup 2 for Exchange Server 2010 Service Pack 3 has been released and may be offered by WSUS on your SBS 2011 Standard server. The update is also available for standalone download and install here .
If you try installing the rollup from Control Panel – Windows Update, you may notice that it fails with the following error:
Additionally, if you have downloaded the Update Rollup 2, setup wizard may prompt you for path to the Installation Package:
You should be able to complete setup by downloading Exchange Server 2010 Service Pack 3 (available here ), extract the installation files locally on the server and pointing the wizard to location of Service Pack 3 binaries. Here is a step by step on the above:
- Download Exchange Server 2010 Service Pack 3.
-
Right click on “Exchange2010-SP3-x64.exe” and select “Run as Administrator”. This will prompt you to specify the location where you want to extract the files. Create a temporary folder where you want the binaries to be extracted and specify the folder path in this dialog box.
-
Once extraction is complete, specify path to this folder in the UR2 installation wizard.
Update Rollup 2 Setup should complete successfully without any further issues.
Above issue is not seen if the folder containing Exchange Service Pack 3 binaries has not been deleted. If you want to confirm the location where Service Pack 3 installation files were stored at the time of installation, you could check the value of InstallSource at the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{4934D1EA-BE46-48B1-8847-F1AF20E892C1}
This workaround can be used to install Update Rollup 2 while we are still investigating the cause behind installation source prompt. This post will be updated as soon as we have an update on this issue.
