regsvr32 fails when registering DAO350.DLL

[gaelxcowi]

As stated, I am unable to register the DAO350.DLL using the regsvr32 tool with the exit code 5.

An exmaple on how I am trying to register it:

$process = Start-Process "regsvr32" -ArgumentList "/s "C:\Program Files (x86)\Common Files\Microsoft Shared\DAO\DAO350.DLL"" -PassThru -Wait; $process.ExitCode and as mentioned I am getting the exit code 5.

Container images that I have tried to run with:

mcr.microsoft.com/windows:ltsc2019
mcr.microsoft.com/windows/server:ltsc2020

I have tried a few things:

Removing the UAC using the following:

Set-ItemProperty -Path REGISTRY::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System -Name ConsentPromptBehaviorAdmin -Value 0

Set-ItemProperty -Path REGISTRY::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System -Name ConsentPromptBehaviorUser -Value 0

Set-ItemProperty -Path REGISTRY::HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System -Name EnableLUA -Value 0

Running in isolation using:

--isolation=hyperv

Running using different account, specifically:

--user "NT Authority\System"

Taking ownership to ContainerAdministrator of the registry nodes and subnodes, as suggested in this blog:

Checking the dependency using dependency walker.

Not sure what I can try more :/ One weird thing, is that I can see that the registry key entry is added once I run the command to:

HKEY_CLASSES_ROOT\TypeLib{00025E01-0000-0000-C000-000000000046}\4.0

with the correct values, etc. but the process still returns an exit code 5.

When trying to run Add-Type of the said .DLL I have the following errors, so maybe some missing dependencies?

Add-Type : c:\Users\Administrator\AppData\Local\Temp\q1ro04mp\q1ro04mp.0.cs(1) : Unexpected character '' c:\Users\Administrator\AppData\Local\Temp\q1ro04mp\q1ro04mp.0.cs(1) : >>> C:\Program Files (x86)\Common Files\microsoft shared\DAO\DAO350.DLL At line:1 char:1
