Question

How to provide publisher Name for MSI installer which is developed using WIX Installer?

While installing my .msi installer it's showing unknown publisher, how to provide a name for publisher?Is it possible to do this within WIX? If so kindly help me how to implement this using WIX installer.

Answer 1

Using WiX's in-built tool insignia is fairly straight-forward. Here's the steps to do code-sign a WiX MSI:

1. Set up the signtool as a batch file in my PATH so that I can call it and change it easily. I'm running Windows 10 and so my "signtool.bat" looks like this:
   "c:\Program Files (x86)\Windows Kits\10\bin\x64\signtool.exe" %*
2. Set up insignia as a batch file in my PATH too so you can change it with new WiX builds as they come. My "insignia.bat" looks like this:
   "C:\Program Files (x86)\WiX Toolset v3.10\bin\insignia.exe" %*
3. Sign my MSI in a post-build event (MSI Project -> Properties -> Build Events) by calling this:
   signtool sign /f "c:\certificates\mycert.pfx" /p cert-password /d "Your Installer Label" /t http://timestamp.verisign.com/scripts/timstamp.dll /v $(TargetFileName)

Further notes and thoughts:

• I have also signed the application (I think) by just doing Project Properties -> Signing and enabling click-once manifests, selecting the certificate and checking the Sign the assembly option.

• Here's my similar answer on how to do the same but for a bootstrap bundle: using insignia to sign WiX MSI and bootstrap bundle

I think you are looking to avoid the security warning that is displayed when someone installs your setup. For this you would need to sign the setup with your certificate and a private key. You can try to do this by following the steps explained in the following links:

• Signing .MSI and .EXE files
• Everything you need to know about Authenticode Code Signing

Assuming you are looking for a publisher name in the control panel Programs and Features. You could use the Manufacturer attribute in your Product tag.

<Product Id="PUT-YOUR-GUID"  
 Manufacturer="PublisherName" 
 Name="ProductName" 
 UpgradeCode="PUT-YOUR-GUID" 
 Version="1.0.0">
