Hi,
There are several possible explanations as to why you’re encountering the error code
1603 when installing Microsoft Flight Simulator X. Here’s a list of the common reasons:
- Corrupted game installation files
- Failure to authenticate the product key you're using in installing the game.
- There are software conflicts that occur when installing the game.
- There are updates available for your Windows 10 device.
- Your device doesn't meet the game requirements.
Let's isolate your concern by answering the following questions:
- Are you installing the game through the setup files you've downloaded or using a game disc?
- Have you tried installing other games to check if the same issue occurs?
In the meantime, we recommend that you perform a clean boot. This process helps eliminate software conflicts that occur when installing a game on Windows 10. Refer to
How to perform a clean boot in Windows for the steps.
I installed by a disc, by the way.
Several months ago, I could run it and played with that dvd on my old win xp PC. And now I have new win 10 notebook (2.4 Ghz, Ram 4gb, VGA 4gb)
Well, I ll try those tips now.
Thanks
