Is this 0.89.8b, or 0.89.8c? I found the former, which matches what you have, but the latter is what I have had issues with, and it looks lighter in size than the former. It doesn't look like a specs problem, more likely some missing files.
First --- this:
The letters after the number just refer to minor bugfixs that have been applied, there should be nothing there at affects your ability to load
Second --- v0.89.8c has been available for download for over 5 months. At least 30,000 players have downloaded it from the F95 links, alone, since that time --- this is the F95 download link from GoFile, showing 15k downloads just from that:
If there were files missing - we'd have known about it much earlier than now.
And before you mention the difference in file size ...
Mega lists files using 1GB as 1,073,741,824 bytes (which is the binary measurement: 2^30)
GoFile lists files using 1GB as 1,000,000,000 bytes (which is the decimal measurement: 10^9)
So Mega will appear slightly smaller in their listing than GoFile's - but they are the same size.
I have now downloaded the Mega version... again... just now... (If you'll notice --- I have already downloaded it previously in order to make it available in my own archive links for players that I have in this thread:
https://f95zone.to/posts/11139721) But I do not remember where I originally downloaded it from and wanted to make sure I was using the exact files you downloaded.
As you can see:
Well, I deleted it entirely. Including the original zipped file
Now you can download it again and extract again to see if there was something wrong in the first time you did that. I would also check to see if your AV isn't incorrectly flagging something to keep it from running.
