The file works alright and, of course, itīs still in my PC. I downloaded 3 versions of the file at the same time, but I canīt remember which one of those 3 I chose to install. Well, my memory doesnīt seem to serve me well any more (by the way, Iīll be 80 in October).
I had a look in ...../Plugins/Extensions (the target folder in installation), I saw the pluginīs folder there, but the pluginīs name only, not the version. So Iīll probably have to either re-install it or forget about the version.
