Hello,

Yes, if you are on SetupBuilder 7.5 then this is the expected behaviour. SetupBuilder Version 7.5 reached "End-of-Life" five years ago on April 23, 2012.

Please see the EOL tab here:

The new or updated redistributables need runtime functionality that is not available in older SetupBuilder versions. For example, support for Windows 8, 8.1, Server 201x, Windows 10, etc.
