Mac OS X - Disc Image Not Recognised

UE4 disc version 1.0.0-2028188 currently available from account page seems to be broken. I tried it on two different computers and both had same issue. I tried repairing it using Disk Utility but it didn’t work.

Hey, Takanu,

What issue are you having with file? I’ve downloaded file again on my Macbook Pro and haven’t had any problems with it. At what point in download/install process do you encounter an error, and what error do you specifically get?

Best,

3

It’s right from the .DMG that can be obtained from account site (ignore the -2 at end, its just because i tried downloading UE4 a previous 2 times)

As soon as I open file it comes up with a prompt saying, “Image Not Recognised”.

Hey Takanu,

It looks like you’re not getting full file. The .dmg file is 46.7 MB, and yours is 5.2 MB. Is something interrupting your download? You might need to check your browser restrictions and firewall.

5

You’re right, this is very strange though. All 3 browsers i’ve tried it on have no restrictions, and they aren’t being blocked by computers firewall. On Safari it downloads 5.2MB before stopping, on Chrome it downloads 5Mb before stopping, and on Firefox it just displays part of data on a webpage in text form rather than downloading it. I’ve never had this issue with any internet downloads before on either computer :confused:

6

To add to this, Windows version has no issues downloading and installing.

7

I am having same problem except I get 35mb’s down… then it stops.

8

same problem here, any solutions?

9

I have same problem with 36.7MB, Anyone?

10

Same problem here, I download 35 mgs and then it stops. Using Chrome on Maverick 10.9.2

11

Could you try downloading using Curl from command line, and attach log?

Open terminal.app and type:
curl -vL DONWLOADURL > UnrealEngine-1.0.0-2028188-curl.dmg

Paste download link from website where it says DOWNLOADURL. Hopefully this will give us a bit more info about what’s going wrong.

12

Please stay tuned – we’re going to set up another CDN (content delivery network) provider for you to try to see whether that helps.

Thanks a lot for trying that out! That does seem to confirm a CDN issue. We’re looking into an alternative CDN host to give you a new link to try.

Also well done on retrying with redirect URL to get farther! I’m not sure why your first Curl attempt failed like it did, as pasting that same command myself works correctly.

15

In case it has something to do, I am trying to download it from Spain.

16

Yeah! Now work fine for me! ,Yeah! Now work for me!

Hey folks,

Here is an alternate download link you can try:

https://s3.amazonaws.com/unreal-engine-installers/UnrealEngine-1.0.0-2028188.dmg

.dmg file you download should be 46.7 MB. If it is not, try this download instead. This should bypass any issues you’re having with incomplete downloads. Let us know if this helps!

18

Thanks, problem have been solved!

19

Yep, this link works perfectly, thanks!

Hello everyone!

We are trying to gather as much info here as we can. For anyone seeing this problem, can you please post following:

  • Are you having problems with just Mac .dmg? Are you able to download windows .msi?

  • What country or region are you coming from?

  • If you are having problems, do S3 links in answer work for you?
