I’ve been completely fine using UE4 up to this version. For some reason it refuses to install. The logs contain the following (full log attached). I’ve been searching the AnswerHub for some time trying to find a fix. I’m installing 4.9.2 to see if I get the same results.
I’m installing UE4 like I have every version previously, through the Launcher. It’s installing onto my E: drive which isn’t an external drive.

We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.
I apologize for the delayed response. Does it kick back an error when you try to “Resume”? If it does not allow for you to resume, please use the remove option then try to redownload if possible. Please post any error messages produces.
Any updates in this? I ran into this exact problem on a fresh Win 10 install: 4.10.2 install fails with corruption, on restart it can’t find download info, on resume it falls into a download-verify loop, 4.9.2 installs fine. Also meant to be installed to c:, an SSD.
The current thought is that there may be a 3rd party app that is blocking the install. The file is failing because we can’t open it, but the files were successfully downloaded and moved. What AV or system monitoring software do you have running?
Good thinking! I disabled Comodo Internet Security and 4.10.2 installed successfully. I supposed to get a notification about every unusual activity but for some reason CIS stayed quiet this time.
