设置 SVN_ASP_DOT_NET_HACK 环境变量

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 confusions with users which always install everything no matter if 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
