Hello @Divya Chinta,
Welcome to Microsoft Q&A forum.
The latest error mentioned that the installation needs the package DiagnosticsHub_CORECOLLECTION_x86.msi
.
Could you kindly check if this .msi file exists on your side? If it doesn’t exist, I would recommend you try to download a DVD/ISO version of Visual Studio 2015. No need to install/reinstall it, but the DiagnosticsHub_CORECOLLECTION_x86.msi
file will be included in the sub-folder. You can try to set the path to point to it and see if the error disappears.
I checked locally, it’s included in vs2015.3.com_enu.iso => packages\DiagnosticsHub_CORECOLLECTION\x86\
Besides, I also tested to install KB5030979(installed VS 2015 with Update 3 first, and then installed KB5030979), it installed completely on my side. I guess the error you met is related to system environment. I suggest you double check and confirm the prerequisites here: Description of the security update for Visual Studio 2015 Update 3: January 9, 2024 (KB5030979)
To apply this security update, you must have both Visual Studio 2015 Update 3 and the subsequent Cumulative Servicing Release KB 3165756 installed.
Have a nice day.
Sincerely,
Tianyu
