What is the error that SOPCBuilder is giving you?

I just downloaded the archive available on the Evidence web site to be sure.

Then,

- I decompressed the archive in c:

- I opened Quartus II 5.0 (from the about dialog box it says build 168 06/22/2005 SJ Full Version)

- then I chose "Project/Restore Archived Project...", and imported the QAR distributed inside the zip file.

- I opened the project (in my case the location is the default given by Quartus II, C:\evidence_demo_2cpu_1_1\evidence_demo_2cpu_1_1\evidence_2cpu_restored)

- and I double clicked on the SOPCBuilder icon, that opened without problems.

Please be sure to use a pathname without spaces, because SOPCBuilder refuses to open a project that has spaces inside the names...

The sequence I just described is the same described in the ERIKA Enterprise Reference Manual. The amnual in any case describes the exact sequence of steps, with screenshots, needed to reconstruct the design: for that reason, I hope there should be no problem to recreate the design for another evaluation board...
