orcad library for 5AGXBB5 not opening plz suggest?

I think the libraries were created using version 15.0 of the tools (that is what the Allegro footprints indicate).

I just opened the 5AGXBB5.OLB in version 16.6, and tried to save it to an earlier version, but the only option is 16.2 format.

If you can find a procedure on how to use the latest edition tools to convert down to Capture 9.0, I'll try it for you. Search the Cadence group, as someone has probably asked in the past.

Cheers,

Dave
