I have install SP1. I have installed prerequisites. I have read of others having this same issue, and in each case it’s something different. One guy needed sp1. One guy had to delete a save file. One guy had to delete a temp file. Obviously there is something deeper going wrong with the code of this engine that doesn’t jive here.

Rig; W7 64bit , i7 920, 8g ram, Zotac 260gtx 1g.
This is a completely fresh install after a hd wipe and os install, using only comodo firewall which has been disabled during attempts to start UE4.14

Hi MIKEFROMSPACE,

Are you trying to install the binary version of the engine from the launcher or the source version from Github? If you are trying to install from the Launcher, are you able to install previous versions of the Engine? Also, if installing from the Launcher, try deleting the DerivedDataCache folder from the install directory and retrying. If this fails to work, try deleting the project from Launcher and trying again. Be sure to verify the installation by selecting the yellow down arrow on the UE4.14 icon and choosing “Verify.”

Let me know if none of the above resolves the issue.
