Unable to Start, Initialization error at startup

Introduction

Initialization errors have different causes and for most of them it’s unclear what’s causing the issue. It’s an error that occurs when the game tries to start-up.

You will receive the following message:

Unable to Start, Initialization error at startup.[135dec40:<Number1>:<Number2>].

The error number has three parts

  • 135dec40: This is always the same. It’s the Initialization error identifier
  • <Number1>: This part gives an indication what’s wrong. Unfortunately for most numbers, I don’t know what they mean and all you can do is do some troubleshooting
  • <Number2>: I don’t believe that part is relevant. Some kind of SessionID probably.

Known Numbers

The following numbers often occur. Some of them have further troubleshooting steps or known causes. If you have those, start with the solutions provided in the linked posts.

General Troubleshooting

Both are important and protect you from a lot of evil around the net. They sometimes do block connections and prevent you from up- and downloading things or from updating your software, though.

Because of this, you should add Origin and EA sites/files as an exception to your programs (refer to the manual on how to do that for your product).

Windows now has a lot of security measurements to make sure external programs don’t harm your computer. This can be the reason that the game doesn’t have enough rights to execute a function and it gets blocked.

The VC++ Redistributables often give issues. You can either repair or reinstall them. Make sure you have all needed versions.

Sometimes it helps to install the All-In-One runtime
