hello all,
I was running 4.6c SR-7 (4.63.0.0409) up until very recently when I've had to completely re-install my windows 10. i was happy with logos 4 and hesitant to upgrade to the higher engines because of the recommended system requirements and hesitant to have a version of logos on my current computer that would be extremely sluggish.
I have tried to re-install logos 4, however, i get the following error on the installation.

i understand there is no longer any support for logos 4 but I was wondering if anyone else was having this problem and was able to successfully re-installed logos 4?
