Having previously downloaded Heartsome Studio and then lost it when my computer died, I went back to the GitHub site to download it but the links for the Windows 64-bit version seem not to work anymore. They take you to a OneDrive page where it says "This link doesn't work anymore. Contact the owner of this item for a new link."
I have now managed to download it, as the Dropbox link does still seem to work. So, if anyone else is looking for this, I suggest you try the Dropbox link first or, at least, don't get too frustrated if you find the other links not working.
One caveat: I haven't tried to install it yet!

It seems that onedrive erased my previous share links as I have not accepted several recent changes in their terms.
And links expired due to this reason or inactlvlty.
Here is the new link to my managed onedrive
Please open and try
I hope you will be able to download it
You can trust the files because I downloaded and uploaded them during the cease period.
