Apparently, almfixed and kurier fonts no longer load as before.
But in this way yes, and I still can't find the reason:
%%%%
\definefontfamily[FAR][serif][almfixed]
\definefontfamily[KUR][sans serif][kurier]
\setupbodyfont [FAR,10pt]

\starttext

123abc\par

\switchtobodyfont[FAR,40pt] 123abc \par

\switchtobodyfont[KUR,40pt]

123abc\par

\switchtobodyfont[FAR,8pt] 123abc\par

\switchtobodyfont[KUR,8pt] 123abc

\stoptext

%%%%
log say:
loaded fonts: 2 files: almfixed.otf, kurier-regular.otf

double-checking the fonts, two still don't switch. this example
procudes a pdf with Latin Modern instead ALM Fixed and Kurier. Any
ideas on how to use those?

\starttext
\switchtobodyfont[almfixed,tt] 123abc \par
\switchtobodyfont[almfixed] 123abc \par
\switchtobodyfont[kurier] 123abc \par
\switchtobodyfont[kurier,ss] 123abc
\stoptext

Luis, the folder you've mentioned does not contain anything that would
resemble Almfixed. Kurier does not have a .lfg file there - perhaps
these are hints at a solution, but I don't know.
