Most likely there are some programs on the system blocking Spectrum installer to install all the Visual C++ Redistributables. You will need to disable the Antivirus and User Access Control and then install Spectrum again. If the problem still exists, you will need to manually install the missing Visual C++ Redistributables.
If Spectrum is successfully installed, you should see these three Visual C++ Redistributables if you open "Programs and Features" from Control panel.
<Please see attached file for image>src="/servlet/servlet.FileDownload?file=0150c000004AK21AAG" alt="09061.JPG" width="691" height="63">
So please compare this above list with your "Programs and Features", and manually run the executable from the relevant directory and install the one which is missing from the list.
vc_redist.x64: This is for Microsoft Visual C++ 2015 Redistributable (x64) - 14.0.23026.
vcredist_x86: This is for Microsoft Visual C++ 2013 Redistributable (x86) - 12.0.30501.
vcredist_x64: This is for Microsoft Visual C++ 2013 Redistributable (x64) - 12.0.30501.
Once all of these three Visual C++ Redistributable have been installed on the system, now you can successfully install Spectrum 10.2
