Hi AI Testani,
Please check your Visual Studio Community 2015, whether it has installed Update 1? If not, please try install the Update 1 first. Then install the Update 2.
If have installed Update 1, please try repair your Visual Studio Community 2015 first to check whether there has any problem in your original installation. And please run your installer as administrator, which can make sure installer has all permissions
to do any operations.
In addition, please use http://aka.ms/vscollect to gather the VS and .Net Frameowrk installation logs. After using it, you will find vslogs.cab from %temp% folder. Please upload the file to Onedrive and
share the link here.
Best Regards,
Weiwei
