Error Code DP-06

Whenever I try to install unreal I get this code and it says I don’t have permission to install it?

did you get around to solving, without running the epic game launcher as admin

You should log in as an administrator or you should be in the administrator group.
For more:

for me it was because the launcher installed itself to the 32 bit program files folder and the engine was pointing to the 64 bit program file location during install. changing the install path for the engine to 32bit program files worked for me. no need for admin login and working as expected

It is weird and nonsense answer because of Windows 7 above honors administrator rights by default.
I think it also applies to Windows Vista because I have never used it.
Just google! You need administrator rights when you install an app, create and edit file or folder to any Program Files in C:\ drive or Windows Installation drive.
Windows 64 bit has both Program Files and Program Files (x86).
Windows 32 bit has only Program Files.
You only change the installation path to Program Files (x86) for Windows 64 bit?
You should do more than that and any Program Files in C:\ drive or Windows installation drive won’t be a problem so why do you need to change your installation folder to Program Files (x86) for Windows 64 bit?
Windows XP ignores the administrator rights so you can install in any Program Files in C:\ drive or Windows installation drive.
Furthermore, why do you need to change your installation folder to Program Files (x86) for Windows 64 bit?


I restate my answer that is log in as administrator.
Administrator launcher or Run as administrator doesn’t work because there is a bug in Unreal Engine itself.
It also applies to Unreal Engine 4.21.

I just had this problem and for me it was because I had insufficient disk space to install all the selected options. So on the same window where it shows you the install path and asks for confirmation, you can choose Options and uncheck all options you do not need for your installation in order to reduce installation size. Either that, or clear some disk space another way.

Hope it helps.

I can confirm. As weird as it is, changing to the “Program Files (x86)” directory works fine.

I also had the same problem and changing target directory to Program Files (x86) works fine. Note: I am logged in with Admin account and still encountered the issue. Also, I have 2 previously installed versions of the engine and they are both in the 64 bit location (Program Files directory). So it does seem to be something weird going on here.

This solved my issue as I ran into the same error code but did not have enough space and I found this post via google

Thank you

For me, I tried running as admin didn’t work, but realized that Epic Launcher was installed in C:\Program Files (x86)\Epic Games, and Unreal Engine was trying to install in C:\Program Files\Epic Games. When I changed it to the same folder it worked.

This is the weirdest issue, I don’t know why there isn’t any official support or documentation about it. changing to the (x86) folder worked. I don’t know why 4.25.4 installs in the “Program Files” yet the 4.26.1 can only be installed in the Program Files (x86).
