I think that the title pretty much says it all.
With VDSP 5.0 Update 8 installed, attempts to create the VisualDSP.ADspSAFP object result in an exception and a crash (return code looks like RPC_E_SERVERFAULT, which isn't very helpful.)
Reinstalling VSDP 5.0 with no updates works. It also works with Update 7. I can provide more details if they would be helpful, but it look easily reproducible.
as VisualDSP++ 5.0 was released almost 3 years ago, there have been a number of bug fixes and improvements to the tools throughout the updates we have issues in that time.
Attached is the release note from VisualDSP++ 5.0 Update 8. This Release note is cumulative and includes individual sections for each of the updates, detailing (among other things) any critical fixes and changes. I would recommend you check these fixes/changes to see if any affect your application.
It is important to note, however, that not all fixes are listed for each update, and we always recommend using the latest update wherever possible. The issues above were introduced in Update 8, so the SAFP works correctly under Update 7. Update 8 will work correctly with the aforementioned fixes in place, and both issues will be fixed in the next update to VisualDSP++ 5.0.
