File Associations

That's my NSIS script to set File Asscociations:

Code:

Section
  DeleteRegKey HKCR ".foo"
  WriteRegStr HKCR ".foo" "" "FooFile"

  WriteRegStr HKCR "FooFile" "" "Foo File Type"
  WriteRegStr HKCR "FooFile\DefaultIcon" "" "foo.exe,0"
  WriteRegStr HKCR "FooFile\shell" "" "open"
  WriteRegStr HKCR "FooFile\shell\open\command" "" 'foo.exe "%1"'
 
  System::Call 'Shell32::SHChangeNotify(i 0x8000000, i 0, i 0, i 0)'
SectionEnd

Seems to work so far.
BUT: Sometimes it's neccesarry to open Explorer, goto Extras > Options > File Types, seach the new file type in the list and click the "Restore" button. If you don't do that, it'll open the files with the old app. Why is that and is there a way to fix it in my NSIS script ???

Seems I found the answer

File Asscociations are not only stored at
HKEY_CLASSES_ROOT\.foo
They are also stored here
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.foo

To set it up properly, it needs to clean up both locations!

Code:

Section
  DeleteRegKey HKCR ".foo"
  DeleteRegKey HKCU "Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.foo"
  WriteRegStr HKCR ".foo" "" "FooFile"

  DeleteRegKey HKCR "FooFile"
  WriteRegStr HKCR "FooFile" "" "Foo File Type"
  WriteRegStr HKCR "FooFile\DefaultIcon" "" "foo.exe,0"
  WriteRegStr HKCR "FooFile\shell" "" "open"
  WriteRegStr HKCR "FooFile\shell\open\command" "" 'foo.exe "%1"'
 
  System::Call 'Shell32::SHChangeNotify(i 0x8000000, i 0, i 0, i 0)'
SectionEnd
