[Therion] Missing mingwm10.dll file

Last week I tried to install Therion on Windows XP and Windows Vista OS machines and each time I tried to run Loch I got an error regarding a missing file, mingwm10.dll Problem was present with 5.2, 5.2.10 and 5.2.12 I eventually had success with 5.2.9 Is this file missing from the former install files or was I doing something wrong? A little perplexing as I have never had this problem on my own XP machine, on which I have successively installed the most recent versions over top of the old versions since about 0.5.1.?
