Treatment of registry entries in connection with file associations
I have already pointed out in another thread to this topic (see on the end of my comment with the subject "research incompletely"). As I suspect, however, that this problem was not noticed sufficiently, I've decided to create this new thread.
Suppose a base app creates in connection with a file association in the registry the following entry:
HKLM\SOFTWARE\Classes\.xyz
At first I assumed that I must make the following entry in the section [RegistryKeys]:
-=HKLM\SOFTWARE\Classes\.xyz
