use VS2008 express as VS2010 native toolkit

I'm about to sw开发者_Python百科itch computer and can't find my VS2008 installation disk.

I only use VS2008 as a native vc90 toolkit in VS2010 to compile an old C++/CLI wrapper assembly. (Haven't opened the VS2008 IDE since I installed VS2010)

Anyone know if it possible to use the c++ express version of VS2008 as vc90 toolkit in VS2010?

I seem to recall that the full VC2008 compiler is bundled with some versions of the Platform SDK, unlike the express edition which IIRC has crippled optimizations.
