Installing VMware Update Manager (version 6.5) from the same installation ISO as vCenter there are two options; install on existing database (typical when VUM is installed on a vCenter server) or to install with embedded SQL Express. The Embedded SQL Express option is only available when Auto-run is selected from the installation ISO.

If you run the VMware Update Manager installer (.exe or .msi) from the “Update Manager” directory, option for Embedded SQL Express is not there and a message is displayed like this –

Remeber, VUM uses 64-bit DSN that needs to be set if selected to use existing database. Once the database option is selected and passed the screen, VUM installs .NET framework 3.5 as pre-requisite. There are two problems encountered while installing the .NET framework 3.5. First, VUM installer tries to install the .NET framework 3.5 and the installation fails. If this happens you may try to enable the .NET framework 3.5 from the control panel –

or, another option is to use CLI command (with administrator privileges). DISM expample –
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All
or (if you have source mounted as D:\ )
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:D:\sources\sxs /LimitAccess

Troubleshooting: The .NET framework installation may fail if installation media is missing or Windows Server Update Services (WSUS) can’t be reached.
Feature installation gets error

DISM installation stuck at 66.5% and subsequently fails with error code 0x800F0906

This error is because Windows host isn’t allowed to download online updates (this is separate from Windows Update). To solve this change the group policy settings to allow optional component installation to contact Windows update.
Run the gpedit.msc and navigate to
Computer Configuration > Administrative Templates > System >
and open the “Specify settings for optional components and component repair” by double-click and then check the box “enable” and “Contact Windows update …”

All is well from here. Run the DISM CLI and .NET framework 3.5 will be installed online without requiring Windows source DVD.
