Unable to install Sitecore 10.1.2 in Windows 11 Pro

Question

I'm trying to install the Graphical setup package for XP Single (Sitecore 10.1 Update 2) on a new laptop which has Windows 11 Pro with SQL Server 2022 16.0.1050.

This is the error during the installation:

Sitecore support has informed that:

Sitecore 10.1 is not compatible with Windows 11 and have never been tested with Windows 11

Unfortunately, I do not have access to another machine with Windows 10.

Added the "TrustServerCertificate": true following this post, but it's the same error.

Is it possible to disable the security SSL check in the Operating system or any other way/hack to complete the installation.

We have 10.1.2 in PRD and that is why I wanted to have the same version on my local machine.

Answer 1

Not sure it will solve your issue but you can also try disabling the TLS 1.3 from your entire system. To do this you need to run the below Powershell script.

New-Item `
   'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' `
   -Force | Out-Null
    
New-ItemProperty `
   -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' `
   -name 'Enabled' -value '0' -PropertyType 'DWord' -Force | Out-Null
    
New-ItemProperty `
   -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' `
   -name 'DisabledByDefault' -value 1 -PropertyType 'DWord' -Force | Out-Null

Try this and see if it works for you.

Another thing you can also try adding a few parameters to your connection string like encrypt=false. To do this if you open your installation folder, there is a file called spe.json. You can see that under "Variables" it is trying to create the connection string. Try adding the values. Not sure if it will work but you can try.

Answer 2

You can give it a try below solutions if that resolves your problem. As per the Microsoft SQL troubleshooting page (Link).

There are 2 more solutions:

1. Use Microsoft OLE DB Driver for SQL Server 18.x. You can download the driver from Release notes for the Microsoft OLE DB Driver for SQL Server.

2. If the application connection string property already specifies a value of Yes or Mandatory for the Encrypt/Use Encryption for Data setting, change the value to No or Optional. For example, Use Encryption for Data=Optional. If the connection string doesn't specify any value for Encrypt/Use Encryption for Data, add Use Encryption for Data=Optional to the connection string. For more information, see Encryption and certificate validation.

The change must be done as explained in this article by adding "Encrypt": "Optional" to 4 instances of Invoke-SqlCmd in xConnect-xp0.json:
