I didn't know you could choose to install VS2008? Generally, vs2008 downloaded from websites is more than 2G in size, but most of the msdn released by Microsoft are aimed at different developers. Msdn is different. The optional installation you mentioned can configure the interface environment for web developers, C# developers and other developers. Custom installation may not kill VB installation when starting vs2008 for the first time. If you want to install VS2008 without VB, you can delete some. If your vs2008 installation package is not available. Exe version (my vs2008 installation package is in. Exe version, so no). In fact, there are a number of books, "Cooperation between Zhang Limin Research Office and Machinery Industry Press", and the CD installation package provided by him is also quite simple. You can refer to his installation package for you.
