Creo 2.0 has a folder located under the Creo 2.0 install folder\Common Files\F001\i486_nt\gcri. Or the same location except that the the i486_nt is replaced with the "64 bit folder name" if the 64 bit software is used.
Copy the file readnewermodels.dll and place this file into the Creo 1.0 install folder\Common Files\F001\i486_nt\obj folder.
You will now be able to open Creo 2.0 files using Creo 1.0

Last year, I remember PTC telling us that from Creo 3 on, you will be able to read newer models. Essentially the rev of Creo you and your vendors are using will become less important as Creo matures.
That was at the time as PTC likes to say "forward looking information, subject to change"
Perhaps it's a corollary to the old software programmer's rule: 'Real programmers never write comments in their code; if it was hard to write, it Should be hard to understand'. Similarly, (or is that 'corollarily'?) if it was hard to write, it Should be hard to find out it exists! I know it's not a Friday, but you have to laugh now & then... John
GCRI - Granite Cross-Release Interoperability, has been around since Wildfire 3 time. It is a plugin to the older version and is limited to 2 versions up. WF2 can read WF3 & WF4, WF4 can read WF5 and Creo 1, etc. The plugin is specific to the read and source pair.
