I'm attempting to follow the instructions according to this post for making an Oracle connection in PowerShell. When I try to load the Oracle .dll I get a operation not supported error.
PS C:\windows\system32> Add-Type -path "C:\Oracle\Oracle.ManagedDataAccess.dll"
Add-Type : Could not load file or assembly 'file:///C:\Oracle\Oracle.ManagedDataAccess.dll' or one of its dependencies.
Operation is not supported. (Exception from HRESULT: 0x80131515)

you can try this way:
[System.Reflection.Assembly]::LoadFrom("C:\Oracle\Oracle.ManagedDataAccess.dll")
verify to have access to folder and unlocked the file.
Was resolved by adding the correct entries in TNSNAMES.ORA and restarting powershell.

I installed npgsql on Windows Server 2022 by the following step.
PS > Install-Package -Name Npgsql -Source https://www.nuget.org/api/v2 -SkipDependencies
PS > Add-Type -Path "C:\Program Files\PackageManagement\NuGet\Packages\Npgsql.6.0.5\lib\net6.0\Npgsql.dll"
However, I got the following error.
Add-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more

Would you tell me the solution?
I have a PowerShell v2 script with .Net 4.5 which compresses old files. Like this:
[Reflection.Assembly]::LoadWithPartialName("System.IO.Compression.FileSystem")
...
$files = Get-Childitem ...
...
$zip = [System.IO.Compression.ZipFile]::Open($arcpath + $curname, "Create")
foreach ($onefile in $files) {
[System.IO.Compression.ZipFileExtensions]::CreateEntryFromFile($zip, $onefile.FullName, $onefile.Name, "Optimal") | out-null
}
It worked fine until I have installed .Net 4.6.1 (which is needed for another project).
Now it throws an error:
The following exception occurred while retrieving member "Open": "Could not load
file or assembly 'System.IO.Compression, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089' or one of its dependencies.

I installed WMF 5.1 to use native ps5 compression functions. But it also throws an error:

How can I fix it?
Deinstalled NET 4.6.1, installed NET 4.6.2. Issue was fixed.
Finally the issue was discovered. We use a custom solution which is using NLog. NLog adds a reference to System.IO.Compression to the solution. During the installation of the solution it deploys the dll (probably the old one or in some improper way). We excluded dll from the installer and now everything work fine.
I need to zip a folder using powershell from within SQLPS runtime. I tried the following from PS SQLSERVER:\> prompt:
$dest = "C:\SomePath\FolderToBeZipped"
$zipfile = $dest + ".zip"
Add-Type -assembly "system.io.compression.filesystem"
[io.compression.zipfile]::CreateFromDirectory($dest,$zipfile)
When run, I get the below error :
Add-Type : Cannot add type. The assembly 'system.io.compression.filesystem' could not be found.

But if I exit out of PS SQLSERVER:\> runtime and execute from normal PS command prompt it is able to compress successfully. Please help how to compress from SQLSERVER powershell runtime. I even tried to invoke a separate .ps1 script (for compressing) using Invoke-Expression from within PS SQLSERVER:\> runtime, but failed. Please help
I'm sending a zip and the powershell script to computers in our organisation through our management software and then executing the powershell script through command prompt. The script unzips the folder, installs a program and adds some registry keys to the registry.
If the machine doesnt say that a policy is preventing execution of the script, it runs as expected, the program is installed and the registry keys are imported. But if it does give the warning and I set the policy to unrestricted I get the below error error. I am on Windows 8.1 and using Powershell 4.0
Id not be found.

anyone have any ideas?
on systems where .NET 4.5 is not installed, use:
$BackUpPath = "C:\Temp\Install.zip"
$Destination = "C:\Temp"
$shell_app=new-object -com shell.application
$zip_file = $shell_app.namespace($BackUpPath )
$destination = $shell_app.namespace($Destination )
$destination.Copyhere($zip_file.items(),0x4)
on systems with.NET 4.5 use:
Add-Type -assembly "system.io.compression.filesystem"
[io.compression.zipfile]::ExtractToDirectory($BackUpPath, $destination)
A script on technet combines the above 2 methods.
On PowerShell V5 , this is much simplified:
Expand-Archive $BackUpPath -destination $Destination
there are other ways to unzip files using 3rd party libraries such as 7-zip, etc but that creates a dependency.
Note: Powershell execution policies can be set using group policy. see link here

If you downloaded the .DLLs from the internet, Powershell by default will not trust them. You can do one of two things here:
Unblock the content. Here's a guide with some elaboration on the problem, but essentially you just need to right-click on the downloaded file, select Properties, and click 'Unblock' in the general tab. You can unblock content directly from powershell by using the Unblock-File cmdlet.
Change your execution policy. This can also allow malicious scripts that you download to run, so be cautious.
Specifically reviewing and unblocking content you trust seems the better route, especially for your case since you seem like you would only be doing this once and you trust the package.
Edit: If that didn't solve that, the other experience I've had with this type of error is when Powershell didn't the same version of the .NET runtime as the assembly. See this question for some context, where Powershell 2.0 ran the .NET 2 runtime and the asker needed .NET 4 for some assemblies.
You're not using the same version of PS so your mileage may vary, but I would try creating/editing a config file per the linked answer to support the runtime of the DLLs you are using.
This worked for me: (from https://stackoverflow.com/a/19957173/107161)
In files:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe.config C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<runtime>
<loadFromRemoteSources enabled="true"/>
</runtime>
</configuration>
Run as Administrator has solved the issue, although my get-executionpolicy is allsigned
