I have a MSI deployment project, I have added Custom Install, remove ,rollback actions in dll. Inside custom install action I am checking some condition ,according to result of the condition I need to rollback the installation. My question is how i will call the roll back action. I saw in some where that we can use

throw

new InstallException("ERROR_MESSAGE");

but this statements gives lot of error like:
install.cpp(222) : error C2061: syntax error : identifier 'InstallException'
install.cpp(225) : error C2143: syntax error : missing ';' before '}'
install.cpp(225) : error C2143: syntax error : missing ';' before '}'
install.cpp(225) : error C2143: syntax error : missing ';' before '}'
install.cpp(225) : error C2143: syntax error : missing ';' before '}'
install.cpp(225) : error C2143: syntax error : missing ';' before '}'
install.cpp(225) : error C2143: syntax error : missing ';' before '}'
install.cpp(225) : error C2143: syntax error : missing ';' before '}'
install.cpp(225) : error C2143: syntax error : missing ';' before '}'


can you help me to figure out what i am doing wrong....

You're probably missing a using reference, something ike using System.Configuration.Install if this was C#. It's no different to any other syntax error you get if you haven't added a reference to an assembly or add a using declaration.
