As of version 1.4.0 and later, the TortoiseSVN installer doesn't provide the user with the option to set the SVN_ASP_DOT_NET_HACK environment variable anymore, since that caused many problems and confusion for users who always install everything no matter whether they know what it is for.

But that option is only hidden for the user. You still can force the TortoiseSVN installer to set that environment variable by setting the ASPDOTNETHACK property to TRUE. For example, you can start the installer like this:

msiexec /i TortoiseSVN-1.4.0.msi ASPDOTNETHACK=TRUE

	Important
	Please note that this hack is only necessary if you're still using VS.NET2002. All later versions of Visual Studio do not require this hack to be activated! So unless you're using that ancient tool, DO NOT USE THIS!
