I have no problem with the antivirus program because I just downloaded The Witcher 3 with almost 8 updates and it installed fine, no problems at all. And I've tried downloading this problem game many times, but it's still the same. I even found similar games, downloaded them, and they had similar updates, and they downloaded and installed perfectly fine, no issues.

Yes, based on your additional explanation, it's even clearer that the problem is not with your antivirus program or a general issue with your computer installing games, but specifically with the "update file" of that particular game, which is consistently problematic.

If you've downloaded the update file for the problematic game multiple times and it's still the same, and you've tried it with other games (including The Witcher 3, which had many updates) with no issues at all, here's the most likely conclusion:

The original patch/update file is corrupted at its source (Source File Corrupted at Source):

This is the most probable cause in your case.

No matter how many times you download it, or from how many places (if it's the same source or a mirror of the same source), the original file of that patch/update might already be corrupted on the server or from where it was uploaded.

This is why the message states, "The source file is corrupted." It means the source file itself is bad, not that it got corrupted during your download.

It's a specific issue with that game's Patcher (Specific Patcher Issue):

Sometimes, a game's Patcher or update installer can be very sensitive or have errors in verifying file integrity.

Or it's possible that the Patcher is "incompatible" with something specific in your system (even though you said other games had no issues, some programs have specific requirements). However, the "source file corrupted" case is more likely.

Further Recommendations:

Try a different download source: If you downloaded this update file from a specific website, try to find it from other sources (if available) to see if the file from a different source is complete.

Contact the game developer/publisher: If it's a legally purchased game or one with a support channel, you should try contacting their support team and report the issue, attaching the error screenshot you provided. They might have a complete patch file for direct download or specific advice for this problem.

Skip that update (if possible): If it's feasible, see if you can skip this particular update for now, or if there's a version available that includes all updates so you can just re-download the entire game (if your current game version is very old).

Since other games and your antivirus aren't causing issues, it's quite certain that the problem lies with the "update file" of that specific game itsel

and All the links that were available to download are dead except for the MegaUp.net link: so it's not surprising that the original file has problems because it's not just me. So it's not because my computer has problems or it can't find the game folder, but the update file has problems.

Can I see when you installed it? You said you installed the game 6 months ago. Or did you take the time to install the game and update it? Can you show me if it's the same?



It wouldn't be too difficult to just take a screenshot and let me see. It'll take about a minute.

pls and thank you
