This installer have the same problem as the game installer, so another "Work around" was deviced.
This installer contains the update in English, French, German, Spanish and Swedish language
THis installer will search for nolf.exe and find the game folder by its own (tested)
Here we go again, click I Agree to begin
My nolf installation is located on G:\NOLF, so that is correct.
And we're installing the update
I fooled the installer a litte and extracted the update to a different folder to see what it unpacked
Files are the original english nolf 1.003 update and the other languages are located in folders
To install these copy everything in the desired folder and paste the files inside the nolf base folder to replace
The guy who made the installer forgot to remove a few files it seems. NoOneLivesForever-patch1.nsi is the actual installer script, it doesn't add anything it shouldn't add
All the files that are red can safely be removed
The installer is complete, v1.004 next...
