Can't GenerateProjectFiles.bat

Hi George, we do apologize for the headache. We’ve only been able to reproduce this issue once, and it might be caused by having 2 different beta versions installed side-by-side at one time. The program association was then unregistered when one of the betas was uninstalled.

We’re currently working on a final fix, but the following work-around should work…

First, please verify that the uproject file is associated with “UE4” and is set to always use it by right clicking → open with. If this is all correct (which it probably is), then try the following…

  • On a fresh computer (no betas installed), install beta3 in the default Program Files location
  • Install beta4 to a different location (can be in a subfolder within Program Files)
  • Uninstall beta3
  • Right click your uproject file → open with → choose UE4 and check “always use the selected program…”

This worked in our single repro case and hopefully for you too. As for the headaches with code projects. We understand the frustration and are trying to check in all painful code changes early on to get it out of the way. While there are always engine changes that require updates in personal code projects, these should be greatly reduced over time.
