Unreal Launcher Installs but doesn't open

Whenever I run the installer for the unreal launcher, it completes the process with no errors or warnings. However, whenever I try to run any of the executables in the shortcuts target directory nothing appears. I have done the steps in creating a log file and the contents are as follows:

I am currently running Windows Embedded 8.1 x64 on a Dell Precision 390 with a 2.4 GHz dual-core processor and 4 GB ram.

Any idea what the problem is and how I can fix it?

Hi diabeticDemon18,

After you installed the Launcher, did you install an engine version under the Library tab?

If so and it still doesn’t open, could you post your dxdiag (system specs)?

  • Windows: Go to the Start menu and type ‘dxdiag’ into the search bar. Open that file and then click ‘Save All Information’. Post that text file here.

Hi diabeticDemon18,

We haven’t heard back from you in a few days, so we are marking this post as resolved for tracking purposes. If you’re still experiencing this issue, please see my last comment above.

Cheers,
