I don't know of a way to prevent that with code. Windows has security measures that prevent unwanted changes to users computers and it will put a block on a file it thinks could pose a threat; DLLs, EXEs, PDFs... If the file is coming from an unsafe place (network or internet) it will put a block on the file.

As you found, you can manually unblock it through the properties. You can also adjust the Group Policies to prevent the blocking. Below is a link explaining some potential solutions, but always proceed with caution when disabling safety measures and ensure it complies with company policy.

Windows Blocking Downloaded Files...

Where are you storing the files? It shouldn't block them if you store them on the local network. But it will block them if you download from the internet, like OneDrive, Dropbox. You may also have security too tight on your local network. This is from Microsoft Copilot.

If you’re experiencing issues with Windows blocking files downloaded from a local network, there are a few steps you can take to address this: Configure Attachment Manager: You can manually configure the Attachment Manager to prevent downloaded files from being blocked. Here’s how: Local Group Policy Editor: Type gpedit.msc in the Start menu search bar and press Enter. Click on the Local Group Policy Editor icon in the search results. Under User Configuration, double-click on Administrative Templates to expand it. Navigate to Windows Components > Attachment Manager. Double-click on Do not preserve zone information in file attachments. Select Enabled and click Apply.

let me explain a bit more on our office processes. we are currently busy with moving away from servers and going full time to everything being in the cloud. for us to be able to use the desktop connector for the cloud we have to zip the .dll files because the deskop connector does not accept .dll files. and it seems the issue comes in when unzipping that it gets blocked. i cannot make any changes to any windows settings as this is controlled by IT which wont allow it. is there any other way to try and unzip the files?

Probably won’t work, but what about renaming the extension, say from .dll to .arx?

Can you deploy using an installer like .msi?

Also you can zip/unzip files with .NET, or choose another compression method

i have managed to solve this by writing a small program to unzip the files and also check if its locked or not and unlock it. this seems to work well. thanks for all the input
