I am trying to install Sitecore 10.4 via Installation Assistant for XP Single and getting the following issue while installing the prerequisites.

enter image description here

Authenticode issuer 'CN="Sitecore USA, Inc.", OU=IT, O="Sitecore USA, Inc.", L=San 
Francisco, S=California, C=US' of the new module 'SitecoreInstallFramework' with 
version '2.4.0' from root certificate authority 'CN=DigiCert Trusted Root G4, 
OU=www.digicert.com, O=DigiCert Inc, C=US' is not matching with the authenticode issuer 
'CN="Sitecore USA, Inc.", O="Sitecore USA, Inc.", L=Sausalito, S=ca, C=US' of the 
previously-installed module 'SitecoreInstallFramework' with version '2.3.0' from root 
certificate authority 'CN=DigiCert Assured ID Root CA, OU=www.digicert.com, O=DigiCert 
Inc, C=US'. If you still want to install or update, use -SkipPublisherCheck parameter.

Did anyone see this issue while installing?

The error message suggests a conflict between versions of the Sitecore Installation Framework (SIF). Let's check which versions are currently installed on your machine to diagnose the issue.

Get-Module SitecoreInstallFramework –ListAvailable

To manually install SIF 2.4.0 with the SkipPublisherCheck flag, run this PowerShell command

Install-Module SitecoreInstallFramework -SkipPublisherCheck -Force

By this the installation should proceed without issues, and the newly installed SIF version will also be included in the list

Now, re-run the SIA prerequisites and the prerequisites installation should be successful.

Thanks @Sreekrishnan for your answer. Yes this was resolved by adding the parameter -SkipPublisherCheck while installing the SIF 2.4.0

While checking the FAQs of SIF 2.4.0 I found the commands to manually install it.


I manually installed the SIF 2.4.0 using this command.

Install-Module -Name SitecoreInstallFramework -RequiredVersion 2.4.0 -force -SkipPublisherCheck

After that, I was able to resolve this error.
