Question

I am building a outlook plugin, for the installer, I decided to use NSIS install script. I have place a check for .Net 4.0 and I am able to download and install .Net Framework 4.0. But, I need some guidance regarding downloading and installing VSTO 4.0 runtime if not present on the client machine.

Basically runtimes that can be downloaded from http://www.microsoft.com/en-us/download/details.aspx?id=20479

I could always check for the presence of VSTO and detect OS and then using hard coded download location which is

for x64
http://download.microsoft.com/download/F/3/9/F395E3C2-28A0-4F0D-9E20-FF4D1ADB08D8/vstor40_x64.exe

and
for x86

http://download.microsoft.com/download/F/3/9/F395E3C2-28A0-4F0D-9E20-FF4D1ADB08D8/vstor40_x86.exe

Download and run the installer.

But, is there any better way of doing this.
