4.7.2 Install issues, looping through verify/repair

I start the Launcher (tried both with or without administrator)
Left column shows 4.6.1 as default
It also shows 4.7.2, 4.6.1, 4.5.1, 4.4.3, 4.3.1, 4.2.1 in the dropdown menu.
In the top main window where you add versions in Library, it also shows each of these in blue and a greyed out 4.7.2.
I’ve seen it downloading 4.7.X on several occasions and for quite a while. I see a download icon up the top between my profile name and the ‘Add a friend’ icon, and a loading bar if I click on that I think.
I’ve clicked on buttons that say verify and repair on a number of occasions for 4.7.X.
After a little while in the launcher, 4.7 will disappear from the dropdown menu and the listed Library large icons.
Whilst in Library the ‘+ Add Versions’ is not functional, and does not respond to clicking.

4.1.2 also has a large icon in the library but is a charcoal colour and in yellow says ‘Install’.
If I remove that icon using the X top left of the icon to ‘Uninstall’ that 4.1.2 icon disappears, and then the ‘+Add versions’ text is then bright and becomes a clickable link.

If I click it, it adds the 4.1.2 back, with no mention of 4.7.X anywhere, so it is not an option to install.

If I close and reopen the launcher I go back to square one, with 4.7.2 being mentioned, but disappears after a while in the menus.

What can I do to get off this non-4.7 merry-go-round?

‘Not installed Unreal Engine 4.7.2’ top left
In library added version 4.7.2, Icon has ‘Create Project’ as the default text. I click downarrow and then I click Verify it says initializing, download icon is up top right corner with a white 1 in an orange circle. Click on it, and Under Pending tasks It shows a loading bar animating which appears to be updating/downloading 4.7.2. It finished and still says Not installed in top left menu, but the main ‘Add version’ icon, has Update, and minutes later now says repair. I click repair and I see 'initializing, and the load bar under Pending Tasks is showing it is downloading again. 10 % in the icon is now saying verifying. When that is done, the default drop down in the large icon for 4.7.2, still charcoal colour, is ‘repair’. After a number of times doing this the default drop down for 4.7.2 library says ‘Create Project’ which does nothing at all when clicked on.

Noting also the Size of all of the downloaded engine versions hasn’t appeared to change from 51.303Gb at all with all this happening.

I don’t believe 4.7.1 was ever really properly installed either. But I have clicked the large icon under the page where you add new versions, but the 4.7 stream has never been in blue (installed colour) and ‘removed’ it. Now I can’t even try to add it again.

Interestingly there was also an added version not fully installed for 4.1.2, and despite continually ‘removing’ it, it would appear as a version ((not blue though). I thought I would fully install that and it would come good, but no, now it wants to only allow an even older version 4.0.X !

Does re-installing the launcher remove all the previous versions? (now at 60Gb worth).


Hi Loucsam,

Have you tried Removing the 4.7 version, then reinstalling? If that doesn’t work, can you also try redownloading the Launcher? Let us know what happens!

If you run the installer again, your installed engines aren’t touched and they will show up in the Launcher again. I’m hoping it will recognize that the 4.7 install isn’t valid and ignore it. Before you run the installer again, go to C:\Program Files\Unreal Engine and delete the 4.7 folder and the 4.1 folder.

Hi Loucsam,

Also, try deleting the ‘UE-4.7’ folder from the VaultCache location. Directions are listed in the excepted answer in this post.

I tried updating this thread at least 4 times to say this is now working, but I don’t see my replies anywhere.

I did indeed remove UE-4.7 from the VaultCache, as I looked around for stuff to delete prior to reinstalling the launcher.

Sorry about that, we are working with our online team to get AnswerHub a bit more streamlined. We see issues like that sometimes too, but hopefully we will see some improvements soon.

Anyways, I’m glad you got it working. Post back here is anything similar pops back up.
