For a fixture to patch automatically in Capture the relevant personality file needs to contain information that links it to the appropriate Capture fixture and the Capture fixture needs to be present in the library (by ensuring the installed library is up-to-date). Where Capture links have been added to personality files any old versions in shows that do not have this information will need to be updated.
The update personality function looks to see if there are newer versions of any currently patched fixtures in the library. This is determined by the history tag. If a personality already patched has a more recent history tag in the library it will appear as an option to update when using the update personality function. [Update All] is a shortcut to selecting the fixtures individually but if no fixtures appear then either the patched personalities are already up-to-date, the installed library is an old version or something has changed in the personality file such as the fixture or mode name preventing it from being recognised. This may be particularly relevant here as the ACME LED-MS700PE was renamed to ACME LED Move 700PE (LED-MS700PE) at the same time as adding the Capture links. So in this case you would probably need to use exchange if you had already patched a version with the old name but if you had already done this then the more recent update with colour function names will appear as an update (requires a library downloaded on 11/11/17 or later).
To simulate currently supported fixtures in a 9.1 show I would do the following:
- Download and install library
- Load 9.1 show
- Update personality (use exchange if necessary)
- Once all fixtures have been updated open the Capture window.
If this doesn't work correctly try wiping the Capture theatre in Capture Settings. If nothing appears at this point try patching a dimmer while the Capture window is open. You can also try turning off auto-update, then wipe, then turn auto-update back on.
It is also conceivable that there is a fault with one or more of the Capture files or that one or more fixtures could be linked to the wrong Capture file for some reason. In this case try patching in a new show. If it doesn't appear in Capture or appears but isn't working as expected when using the latest library then please submit a personality request or bug report respectively (except for the Chauvet Intimidator Duo of course

)
PS. thank you for pointing out the incorrect information in the manual. I have added a task to review the relevant sections.
