I can run " Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:E:\sources\sxs /LimitAccess " code in Command Prompt.
What I wan't to do is to run this code through Vb.net application.
Use the Process.Start
API to do this
System.Diagnostics.Process.Start( _
"Dism.exe", _
"/online /enable-feature /featurename:NetFX3 /All /Source:E:\sources\sxs /LimitAccess")
Note that you will possibly have to provide the full path to dism.exe
