Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Prerequisites have failed to install. Error Code: SU-PQR1603 & Windows Error: 0x80070643

Just got in a new PC so this is a fresh install of Windows 10. I cannot install the Epic Games Launcher, it failed when trying to install prerequisites. Link to screenshots of failures: https://imgur.com/a/YZjst

Here is a list of everything I have tried:

  1. Manually install of prereqs in this article http://fortnitehelp.epicgames.com/customer/portal/articles/2289966-prerequisites-have-failed-to-install-when-installing-the-epic-games-launcher

  2. Updated Windows to the latest version

  3. Reset the Windows Installer service

  4. Grant Full Control permission to all user accounts and System account

  5. Try installing on both C: system drive and D: storage drive

  6. Manually run the "LauncherPrereqSetup_x64.exe" at "D:\Program Files (x86)\Epic Games\Launcher\Portal\SelfUpdateStaging\Install\Portal\Extras\Redist"

  7. Restart the computer

I have run out of options to try. I even grabbed the .msi from the temp program data as the LauncherPrereqSetup_x64.exe was running and ran that, still nothing.

Included are my dxdiag and log file from LauncherPrereqSetup_x64.exe.
