Reason I ask is that I have an ongoing PBEM on 1.10c, but have also installed 1.14 for a new PBEM. It's a new computer. I did a clean install, copied it to a different folder, and patched the first (the original install) to 1.14 and the copy to 1.10c. I played one turn fine on 1.10c, played another on 1.14, but now the 1.10c version crashes a few seconds into starting up, while the 1.14 still starts fine.
Are there any conflicts with running two parallel versions? Is it possible at all? Should I have done two clean installs? Any other safeguards against known conflicts?
Any helpful comments would be most appreciated.
