Getting an error BV03 when installing UE4

Development Getting Started & Setup
, , ,
1

I get an error code during verification step of downloading the UE4. It says: “The installation is corrupt. Please contact Support. Error Code IS-BV03” but I can’t find anything online related to that error code. I think some of the pertinent parts of the log are below. EDIT: Full log message is here: Dropbox - Error

I’m on OSX 10.13.6.

Thanks for your help!

Hello? Anyone there? It’s been almost 2 weeks… I’d love to get this resolved. I’m teaching a game design course to some homeschool students, but I can’t get past the install. We might have to switch to Unity if I can’t get the environment up and running :frowning:

Hello? Still looking for some assistance.

Same here, 4.25 and 4.26 but I was able to install the 4.3. :confused:

disable you windows defender, firewall and antivirus. Try again. :slight_smile:
