error code C000001D illegal instruction
Closed, ResolvedPublic

Description

Since update 1.26 I keep getting this error code every time I start the game. The game has been reinstalled, files verified, battle eye has been reinstalled and this error keeps happening. I had almost a minute of play with update 1.28 before it happened again and went right back to crashing with this same error on startup. I tried running the game as an administrator (update 1.28) and got as far as the survivor load page before it crashed again.

This is the issue, this is an old and unsupported processor. Unfortunately the game will not run on this hardware.

Geez claimed this task.

Game hardware specs should be updated to reflect this, it ran fine for 800+ hours with the current hardware prior to the February update.

The CPU you have been using is below minimum requirements that are listed at the Steam store.
The fact the game ran previously was unfortunately by pure luck and we cannot guarantee the game continuing to work on below minimum spec hardware.
