fkj, I checked
viapfd100.exe file, but RAR header of the last file is really corrupted (even WinRAR says: "
D:\Downloaded\viapfd100.exe: The file "" header is corrupt" - all files are extracted & scanned (or installed by that self-installation app) without any problems.
Since RAR file is in EXE, it's not easy to say if the archive was really corrupted or not (because I can't know if the last file is really the last one - and then some binary garbage behind its, or corrupted header of the next file) - but I'm going to do little fix into the next build.
Heroes saved game files are compressed with
GZIP, I could get the original valid unpacked file - but with unknown reason,
.GM1 files have invalid CRC value at the end of the file.
