Thanks for your response.
I am able to install SMP 3.0 SP03 on windows 8.1 successfully but when i apply upgrade Patch level PL 01/PL02, i get that above attached pop-up.
can you please send us the install logs for us to look into the issue please
There is no log generated for this upgrade process. As soon i click on "setupAMD64.exe" file (Run as Admin),i get that pop-up. What do you say?
Rgrds,
