   NSIS installer vista problem
  so i got my programm and i want to distribute it, but now the problem is this: I'm on vista so if the programm wants to edit any of the other files shipped with the installer i get a "an unprosecced exeptional .NET" error that it can't get acces to the files. So i googled to see how i can avoid it.i downloaded a plugin called "AccesControll" and used this call:Quote:  AccessControl::GrantOnFile "$INSTDIR\me.his" "(BU)" "GenericRead + GenericWrite"it worked with one file, so i added more but now it is complaining about all the files (same "unprocessed error").can anyone tell me how to solve this?  assainator   
  where are these files being installed?I ask, because the security system in post-Vista means you shouldn't be writing files which needed editing/changing by your app into your programs install dir. They should be written into locations which already have the correct permisions for the files; this link has more information.This is the CORRECT way to do things, you should NOT be changing the permissions of files behind the user's back.   ;  thanks for the advice it works very good now.and i didn't mean that a exe would have permission to poke arround in somebody's files, but that for example a text file could be editted by a programm.   ;  Yeah, that wasn't so much what I was saying.It's more a case of files installed in the Program Files directory should only be writeable by a process which has full admin rights and readable by everyone else.
