Multiple install Directories?

Is it possible to set multiple install directorys so that when I install to $INSTDIR it installs to all the directorys?
Thanks in advance

Yes, simply extract the files multiple times to whichever directories you wish. For example:

SetOutPath $INSTDIR

File blah.dat

SetOutPath $PROGRAMFILES\Blah

File blah.dat

I'm actually using WriteToFile so this doesn't work.
Another option for me would be to copy it.
Any Ideas?

As with File, you can call WriteToFile multiple times. There is no magic solution here, either you copy it or you write it twice.

Thanks anyway
