I just learned how to use Winrar to pack files as an SFX to create a silent installer. However, I would like the installer to move a file or two during installation. In other words I would like to have example.dll to be overwritten with example.dll from another folder. I couldn't figure out how to do this with Winrar. Do I need to use something different?

Right click .dll, add to archive, click make sfx archive, go to comment tab, add this:

;SFX

Path=%systemdrive%\windows
SavePath
Silent=1
Overwrite=1

Change path to the folder where the .dll you want to override is located.

Right click .dll, add to archive, click make sfx archive, go to comment tab, add this:

;SFX

Path=%systemdrive%\windows
SavePath
Silent=1
Overwrite=1

Change path to the folder where the .dll you want to override is located.

Ok, I understand. But what if I want winrar to run an installer, and then overwrite a file in the program file directory. For example, I want the sfx to run example.exe and then after installation to copy/overwrite example.dll to C:\Program Files\Example Program.

Various indirect options are available with this kind of installtion via WINRAR

1) use 2 winrar exe. 1 for setup, 2nd for override only, like Raoul90 comment example

2) Use a batch file to control/install. But you will get console window open during installation.

I generally use hstart.exe to hide the console to achieve fully silent effect

3) Use Autoit with WinRAR

The above can be achieve using an alternative good tool (it's a console tool):

Hope that helps...
