Dialog editor allows to set min/max values in any range and in test mode it works properly. However installer assumes min/max as 0->100 and works this way. Am i right?
Normally yes - however, you can actually control the position of the progress bar manually in the script, so you can set the Max to 1000 and manually set the position to 100 (and not fill the bar totally).
> you can set the Max to 1000
this is what I'm doing
> manually set the position to 100 (and not fill the bar totally).
and the bar is filled totally
Simple check it.
