Win32 App Powershell 64bit registry access issue

Hello to all.

Coming from SCCM to Intunes i started to recreate Application packages, with installers based on MSI, Batch, EXE and PowerShell. However i found an issue with PowerShell installations, that i am not able to overcome.
Powershell is not accessing 64 bit registry, due to Intune agent running the script in 32 bit mode.

For example when i try to write a key (or value) to HKEY_LOCAL_MACHINE\SOFTWARE\Test, it stores the key in HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Test

I am partially able to go around the issue by importing .reg files or adding keys/values in batch or PS using reg.exe with operator /reg:64  For example:

reg import "%~dp0import.reg" /reg:64 /f

reg add "HKLM\SOFTWARE\Test" /reg:64 /f

This is OK when i want to just write keys and values.

However when trying to read current registry and create new, or modify existing values i am not able to read/write the registry due to powershell running in 32bit mode and redirected to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node

For Example installing draftsight that uses the same  license manager client as solidworks. 

If solidworks is installed, license server registry entry is added, if not present. If solidworks is not installed  key and value is created:

$flexreg = (Get-ItemProperty "HKLM:\Software\FLEXlm License Manager").SW_D_LICENSE_FILE
Start-Process -Wait -NoNewWindow "msiexec" -ArgumentList "/i","$pwd\DraftSight.msi","/qb","LICENSETYPE=3"
if (!$flexreg) {
    New-Item -Path "HKLM:\Software" -Name "FLEXlm License Manager" -Force
    New-ItemProperty "HKLM:\Software\FLEXlm License Manager" -Name "SW_D_LICENSE_FILE" -Value 'portnr@servername' -PropertyType STRING -Force
} elseif ($flexreg -like '*portnr@servername*') {
Exit
} else  {
    New-ItemProperty "HKLM:\Software\FLEXlm License Manager" -Name "SW_D_LICENSE_FILE" -Value $flexreg';portnr@servername' -PropertyType STRING -Force
}

I was searching the web for few days now and i am not able to find a solution.

I have found few articles for using SysNative, but that is not present in Windows 10 anymore

I tried to use 64bit powershell to start the program: %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass -File registry.ps1

Same outcome , powershell is forced to 32 bit mode.

I tried to force the path:

New-Item -Path Registry::HKEY_LOCAL_MACHINE\SOFTWARE\ -Name "Test" -Force
New-ItemProperty Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Test\  -Name "testproperty" -Value 'testvalue0000' -PropertyType STRING -Force

Which does not even write to HKEY_LOCAL_MACHINE\SOFTWARE\Test or  HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Test.

Running the scripts as local admin on the PC works off course.

I hope someone can point me to a solution. Thanks in advance for your donated brain power.
