Looking for older IPP version

Hi.

I'm trying to rebuild a software project from about 2009-2010. I might port it to a newer IPP version later (I actually tried but this takes too much time at the moment), but at the moment I am looking to make the project usable again as easily as possible. I am not sure what version was initially used to build the project. Is there somewhere to obtain an IPP this old? How?

Cheers,

Kaspar
