I’m very sorry for failing to get back to you before now.
I’ve looked at the log files you provided - thanks! - and the error is, fundamentally, that the launcher downloaded something from the server, and then found it had changed on-disk.
You mention having reformatted the SSD. Do you remember whether you performed a quick format? If so, it won’t have performed a check for bad sectors. I’d like this to be performed.
Here’s how you can do so;
- Search your computer for
- Click on it when it appears in the results
on the drive you are attempting to install the game on (usually the C: drive)
- Click on
- Switch to the tab
- Click the button in the Error Checking section
(You may be prompted to confirm you wish to scan the drive for errors)
The above will result in one of the following two messages appearing;
Your drive was successfully scanned. Windows successfully scanned the drive. No errors were found.
Restart your computer to repair the file system. You can restart right away or schedule the error fixing on next restart.
If the second one is shown, please restart your computer so Windows can attempt the repair. It will automatically open a window to tell you whether it was successful, however it may be a few minutes before this window appears. This is normal - it will happen eventually.
After doing the above, please delete the installer & the partial install it has created, and then perform a fresh download of it from this page and begin the installation procedure again.
If you would prefer not to try troubleshooting the issue: people who buy Last Epoch outside of Steam can link their Last Epoch and Steam accounts to play the game on Steam without buying it again. If you’re interested, please see this support article for more information.
(I’d suggest following the advice above regardless - if there is a problem, it should be fixed.)
