Just updated to 2.6.0, stopped the services, ran the update and all went smoothly. Went to start the services and got:

"Could not start the BuildMaster Web Server (INEDOBMWEBSRV) service on Local Computer. Error 1075: The dependency service does not exist or has been marked for deletion."

What can I do to fix this?

If you run the command:

sc config inedobmwebsrv depend= /

for the web server or:

sc config inedobmsvc depend= /

on the server with admin privileges, the dependency should be removed.
