SymIM.sys install error

So I can't run NIS2009 because my machine won't boot with NIS09 and my ATI card so I am still running NIS08 but yesterday NIS08 refused to install an updated component so I decided to uninstall and reinstall and see if that worked...

 

Now even after running the NRT several times each time I try to install NIS2008 it tells me it needs the file "SymIM.sys" on the Symantec Network Driver Disc and it expects me to find the path to it...

 

Any ideas?
