Visual Studio 2015 installation issue - SqlDom_amd64\SqlDom.msi

Question

I am trying to install Visual Studio 2015, however, after several steps, Installer pops up one message as below,

I cleared %temp% files however,it did not work either yet. It is not package issue because that this package was installed successfully in another WIN7 system.

Answer 1

The real problem is that your windows is missing some Microsoft certificates, to verify if this is the case:

1. Open certification manager (Win+R -> certmgr.msc)
2. Go to "Trusted Root Certification Authorities" -> "Certificates"
3. Check for:
   • "Microsoft Root Certificate Authority"
   • "Microsoft Root Certificate Authority 2010"
   • "Microsoft Root Certificate Authority 2011".
   • You most likely don't have all of them from some reason.

On other PC that is connected to the internet and receiving Microsoft updates:

1. Check again for these certificates, you most likely see them.
2. Export them to SST file.
3. Import the SST file (that contain the 3 certificates) in the first PC.

Install again, now it will work :-)

I believe that this will also fix some Visual Studio 2013 SDKDDKVer.h and related errors.
