Custom Framework2.0 installation using web application

Hi,

I have to install a printer component

i have created a printer component(dll) which needs .Net Framework 2.0 support. I got the printer component installation as a .msi file. I would download the .msi file using <a href. ....> Printer </a> tag. If the client machine has framework there is no problem in installing the .msi component. But if the client machine does not have the .Net Framework2.0 the .msi file needs to fetch the dotnetfx.exe from the server location in tha application as ~/downloads/donetfx/dotnetfx.exe . I need to modify the launch condition for .Net Framework. Please suggest what can be done so that the path can be specified trom relative url.

Thank you,.
