Hello Srikanth,

An upgrade is a two step process. Firstly, the older version is uninstalled from the computer and then the new version is installed replacing the old version. In your case, the new DLL is not copied into the system because the older DLL has a higher version.

In the "File Versioning Rules" article, it is specified that:

Highest Version Wins—All other things being equal, the file with the highest version wins, even if the file on the computer has the highest version

Can you please help me on Upgrade, it should copy the DLL if it older version.

I am afraid that what you want to achieve is not possible. You can increase the version of your new DLL so it will be higher than the version of the older DLL.
