.res files format

[Horrid]

I have this res file that adds values to the registy but the path doesn't work, I can put filename.dll but not path\filename.dll

and ideas?
[HKEY_CLASSES_ROOT\CLSID\{57645A55-64CF-11D5-A196-00E07D8A45E8}\InProcServer32]
@ = &quot;c:\tltoolbar\toolbar.dll&quot; <--problem line
&quot;ThreadingModel&quot; = &quot;Apartment&quot;
