I am new to PureData and have no idea why the following are displayed after right-clicked>help:

What do they actually mean, plus more importantly how can I fix them?
Thanks in advance.

@elly0t Hello there......
[midiin] and [sysexin] are not supported in windows. Some people have written patches to get around the lack of sysex, and instead of midiin you can use [ctrlin] [notein] etc.

[powtorms~] [mstopow~] do not exist as far as I know even in vanilla for windows, and in the windows extended 0.43.4 release they do not. I remember seeing that they were in a Linux vanilla build, and in a very old Pd build for XP.... so you might be able to find them......... someone might have built them as an external that you could add to your pd/extra folder and then use them like any other object. If you have opened someone elses patch then it is possible that they used those objects in that patch, but you do not have them so they will not "create" and will just show the name in a red dotted box instead of a solid black outline.

[scalar] does not exist, but [scalar-help] does and that explains how to use scalars....... which use other objects but not [scalar]
So, basically, not all objects exist in all versions of Pd, and certainly not under all operating systems.
