Change the installer size
Hi!

I've made an online installer using NSIS. I calculate what should be installed during the installation. However, when I select destination folder, the installation size is all wrong. I have the correct size in a variable - how do I change the installer size in the destination folder window?

Can I create a custom destination folder window?

I use code similar to this, which you might have to tweak in some places to make it work for you.


SRCDIR

>Var SIZE


Section"InstallFiles" id1

  SetOutPath "-"

 File "${SRCDIR}\*.*"

>SectionEnd


>; False section

Section"New_Size" id2

SectionEnd


>!define SetSize "Call SetSize"


>Function SetSize

  StrCpy $SIZE"6474381" # ; size in bytes 

 ; bytes to kilobytes

  IntOp$0 $SIZE % 1024

  IntOp $SIZE $SIZE/ 1024 ; rounded down

  IntCmp$0 512 0 +2 0

  IntOp $SIZE $SIZE+ 1 ; rounded up

  SectionSetSize${id1} 0 ; clear size estimate

  SectionSetSize${id2} $SIZE ; reset the size

FunctionEnd


>; Directory Page

>Function DirectoryPageShow

  SectionGetSize${id2} $2

 ; Required space (reset)

  ${if} $2 == 0

   ${SetSize}

  ${EndIf}

 SectionSetSize ${id2} $SIZE

FunctionEnd

Why not? The NSIS directory page is pretty good though.
