How can I tell what versions of Calypso a Measurement Plan is compatible with?

[[Aa...]]

I have a measurement plan created on our programming machine, running Calypso 6.0.12 with Planner.  The plan opens fine on two operating machines without Planner, one running 6.0.08 and the other running 5.8.28, but another operating machine running 6.2.12 without Planner refuses to open it.  How does one troubleshoot a situation like this?  What's most baffling is that the one where the plan won't open has a newer version of Calypso than any of our other machines.

Actually, the plan shouldn't open with 5.8!?
Can you try saving the plan under a new name on 5.8?

[[No...]]

Within the same main revision plans should always open. There wer a few cases where the next lower main revsion was also still able to open a plan saved in a newer one.

But that the higher revision won't open it is indeed strange. Can you rule out any shady activities (like meddling with version strings as is sometimes suggested) or a damaged file? What is the exact error message?

I wasn't at the machine when attempts were made to open it, so I wouldn't have personally seen the error messages, but I was told that it just sat there like it was trying to load, but would never actually finish loading.

We've been running with our current versions for years (ever since we bought the third CMM) with no issues, so I suspect you're on the right track.  I want to investigate further, though I will likely have too much on my plate over the course of the next month.  Norbert, could you please provide me with whatever information you think I need to know how to check whether something has happened to alter the version string(s) or the file has been damaged?

A workaround i was told about but haven't personally tested for sending programs to older rev machines, is to copy the program and delete the file called "revision". 

Its a text file and only consists of a single line of text, 6.8.08 or something like that.

The thought is that if calypso senses that it is missing it will create a new replacement file.
