Windows 8.1 installer .msi error 2503, then 250

I have seen the similar question: Can't install UnrealEngineInstaller.msi, error 2503 and error 2502 - Getting Started & Setup - Epic Developer Community Forums

But I have full permissions on my drives, program files, etc, and I am still getting the error.

Log is here

I should note that I had to move the destination of the log file like so:
msiexec /i C:\UnrealEngineInstaller-1.1.0-2054669.msi /L*V C:\test\UnrealEngineInstallerLog.txt

or I would get the following error:

[Window Title]
Windows Installer

[Main Instruction]
Error opening installation log file. Verify that the specified log file location exists and is writable.

[OK]

(Which is suspicious, but I have triple checked that my account has Full Control of the C drive, as well as program files.)

try to download the setup file again and run it with admin rights

My account is the admin account. For kicks I made a standard local account and tried that as well, no dice.

It seems that this issue can be seen for a few reasons. So far I have found the following will cause this or similar issues: Invalid permissions on the target install folder, incorrectly set system date, or Invalid permissions on the Windows Installer temp folder( Link1) ( Link2 ).

Since you have double checked the permissions on the target install folder we’ll need to check the other two. According to your log, it looks like the issue may be invalid permissions on the C:\WINDOWS\Installer folder. Check out the links I provided which give some info on how to adjust the permissions on this folder.

I also am having this problem on a fairly new Win8.1 box. The permissions look ok; I have tried un-registering and re-registering msiexec. No dice.

Have you tried running the installer as Administrator? Check out the links in the other answers to this thread. Also, we would be happy to look at your logs to see if we can pinpoint the issue.

Yes I solved it by installing it from an Admin command line prompt. Didn’t realise it wasn’t taking admin permissions for itself.

Just posting another solution for anyone else that comes across this. I was getting the 2503 /2502 error and I did this:

  • Open Task Manager
  • Under the ‘Processes’ tab, right-click Windows Explorer and ‘End
    Task’
  • Click ‘File’ > ‘Run New Task’
  • Type “explorer.exe” and tick the only box there that says “Create this
    task with administrative privileges”

Hope this helps someone! Even with admin privileges on, the install wasn’t working for me until I did this.
