Modify the Space Required
I need to change the Space Required option, which we get while installation to a space which I determine from a INI file.

I tried AddSize, but issue with AddSize is that it doesn't take a variable as input.

How can I resolve it?

I have added following code.

SectionGetSize $R1 $5
IntOp $5 $5 + $4
SectionSetSize $R1 $5

$R1 is the sectionId, $4 is the size need to be set.

Even after doing the same I see Space Required: as 0.0KB

Why is your sectionID in a variable? Are you enumerating all sections, or something like that?

As for the space being zero, at which time are you setting the section size? In .onInit?

I create section dynamically, (i.e.) while executing only I determine the sections, thats why the sectionId is in variable.

I set the size for each section during .onInit

- Are you sure your dynamic sections are enabled AND selected properly?
- Use MessageBox to verify the value you're setting the size to
- Use sectiongetflags or something similar to verify the section ID's you're using.
- I don't know if NSIS automatically uses incrementing numbers from zero for section IDs. Better to set them to 0, 1, 2... manually when you define them.
