Currently running DC version 10.0.93 on virtualized VMWare server running Windows 2012R2.  Have been routinely applying update patches thru use of the UpdateManager in the bin folder.  Went to do the latest update and nothing happens when I run UpdateManager, either by double clicking or by right clicking and "Run as Administrator" or by opening a command box and typing in UpdateManager.  If I run it by double clicking or right-click-RunAsAdministstrator then I get a quick flash of the command window which then closes.  If I open a command window and run Updatemanager then it just does nothing.

To my knowledge, no changes have been made to the server other than normal Windows updates.  It has been running virtualized on same operating system for 2 years or more.

Please help me figure out why UpdateManager has suddenly stopped launching the Update process.

Thanks.
