Hi
You need to extract the files from the ISO file into a separate folder. After this is completed, locate the Setup.exe or Setup.msi file and double click to install.
I recommend using the free 7Zip utility to extract the ISO.
7-Zip:
After 7Zip is installed, right click the ISO file and use the 7Zip options to extract the file.
After Visual Studio is installed, you can get support at the following forums.
