I used the MSI configuration tool to create a new package to replace an older version I was running. The older version (6.10.5 I believe) just installed, never asking questions, no pop-ups, nothing, totally silent.
The new one, even when I check the box to "Do not ask for confirmation before installation" still pops up a box asking a question (see attached).
I have tried twice, the second time making absolutely sure I checked that box, same thing. Other than that the installer works fine.
Unfortunately, this feature was discontinued starting version 7 of Remote Utilities. For more information please also see our Release Notes. However, since you're using version 6, I've forwarded the question regarding this issue to our developers to check with them if it might be expected behavior. Sorry for the inconvenience.
I'll get back to you with an update on this shortly.
