Hi,

I wanted to create a profile with "Musescore 3.6"
but 3 times it failed during building process.

So I had to create the profile with "Musescore 4".

Now I have Musescore 4 in my main profile and in my Musescore profil.

So the problem is now, how do I know when opening "Musescore" which one 
will open.
Using the menu it opens "musescore 4" in my main profile
Using an icon it opens "musescore 3.6" the earlier version, which I need 
as well.

1.
if I enter "musescore" in my bash
it doesn’t open this package.
Why?
If this profile is open/sourced, it should open this package.
Other packages from my main profile like icecat, gedit, pluma open 
immeadiately.

......................................................................
Today, without doing anything
I did a:
guix package -p /home/gfp/Projekte/Musescore/guix-profil

and the outcome was:

gfp@Tuxedo ~$ guix package -p /home/gfp/Projekte/Musescore/guix-profil 
--list-installed
musescore	4.0	out	/gnu/store/7iwmb7qf56ybrl0ayzyr3w14h3azdg8p-musescore-4.0
gfp@Tuxedo ~$
......................................................................
This means I was already in this profile, or better to say, both 
profiles were open at the same time
without sourcing it today.

This means for me that, when I tried to source this profile earlier,
I opened it, but didn’t manage to close it.

2.
Is it better to close it, or leave several profiles open at the same time?

3.
Is it a problem when both/more profiles are always open?


4.
what does it mean for my bash/MATE terminal?
Shouldn’t I be able to open "musescore" in both profiles?
Is so, what do I have to enter in the bash to open this or that "musescore"


I am hacking on the very basics

Kind regards

Gottfried
