Solved [Solution Given] Out of Memory Error During Fresh Installation on Windows 11

■ System Environment

• OS: Windows 11 Pro 24H2
• RAM: 64GB (Kingston FURY Beast DDR5 32Gx2)
• Disk Space: C: 621G free, D: 598G free
• Installer Files:
  • MapleRoyalsSetupWzFixed-09.06.25.exe
  • MapleRoyalsSetupImgFixed-09.06.25.exe

■ Steps to Reproduce

1. Download the two official installers mentioned above.
2. Run MapleRoyalsSetupWzFixed-09.06.25.exe (or the ImgFixed version).

■ Actual Result
"Out of Memory" error message is displayed.

■ Expected Result
The installation should complete successfully without any memory-related errors.

■ Troubleshooting Steps Taken

• Restarted the computer.
• Closed all other non-essential programs.
• Ran the installer with "Run as administrator" privileges.
• Set the installer's compatibility mode to both Windows 7 and Windows XP (Service Pack 3).
  

■ My Analysis / Suspected Cause
I suspect the issue stems from the installers being 32-bit applications. A 32-bit process has a memory-addressing limit of 2 GB. It appears that one or more of the .wz or .img files being processed during installation exceed this limit.

As a result, the installer process runs out of addressable memory space and crashes, even though my system has more than enough physical RAM.

 

Make sure you have Core Isolation off

I had a different memory issue and this helped resolve for me.



Also check the below regedit settings

Code:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\CredentialGuard

REG_DWORD should be 0.

Code:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity 

REG_DWORD should be 0

 

My core isolation has long been turned off.
The value of `Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\CredentialGuard` is also 0.
And I cannot find `Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity` in my regedit.

```
