I figured out, that the following DLLs are needed to be in CERTI path:
- iconv.dll
- ieshims.dll
- libgcc_s_dw2-1.dll
- libxml2.dll
- zlib1.dll

iconc and zlib1 are mainly dependencies of libxml2, and it seems that
certi.dll is dependent on libxml2.

Other dependencies are LIBSTDC++-6.DLL, WS2_32.DLL and MSVCRT, but these
are not found in other directories, and is working therefore.

If you wish, I can send you the whole DependencyWalker output as txt file.

No, unfortunately not.
