--- Comment #5 from tkocou@protonmail.com --- At first, I installed 7.0 on top of the existing 5.0.3. Errors of course. I purged 100% of the WINE installation via the synaptic manager to include deleting the .wine directory. I installed the 7.0. and made sure that the winecfg pointed to the 7.0 version. Still the same errors about missing DLLs when I invoked winecfg. So I repeated purging 7.0 and installed 7.9 dev version. Same errors again. So I purged the WINE installation, installed the older 5.0.3 (via synaptic) and overwrote the .wine directory from a known good backup. winecfg is working now.
