What version of MsXml is used as default by MsXsl.exe

Hi Team,

We currently have MsXml versions 3.0, 4.0 and 7.0 on our Windows 2012 server. We use MsXsl.exe to process xslt files into csv in our application. MsXml version 4.0 has been flagged by our infra team that it should be removed as it is no longer in Microsoft support. We found that MsXsl.exe we use is of version 4.0 and assume it consumes MsXml 4.0.

Could you please help us with below questions,

1. How to find what version of MsXml is called/consumed by our MsXsl.exe(4.0)
2. What is the default version of MsXml for MsXsl.exe(version 4.0)
3. How to manually force MsXsl.exe to point to a different MsXml version
4. The latest version of MsXsl.exe we could download from (https://www.microsoft.com/en-au/download/details.aspx?id=21714) is 3.0. What version of MsXml will it consume by default ?

Thanks and Regards,

Vino
