Signed version of the Hubshare application

Where did you get the download from?

The M-Files Catalog is the place where these are published, and there are much newer versions than 23.1 available, all of which are signed: M-Files Plugin for Hubshare | M-Files Catalog

Of course, I downloaded it from the M-Files catalog. There are several versions available, and I tried with version 24.12 and then version 23.12.

I haven't checked with Hubshare but is the download an mfappx file or a zip? Do you need to unzip it to find the actual installer? 

I would like to clarify that we are using the cloud version of M-Files. We have seven vaults that were copied to the server by the M-Files support team. In my local vaults, I can add applications like AINO and others without any issues. Does adding an application require intervention from the support team? Otherwise, the file I download is in ZIP format.

Installing signed applications is supported in the cloud.

I have finished for the week so not near my laptop to test, but what is inside that zip file?

Edit: I opened it from my phone to check. You should install the actual zip file. You should not install the inside mfappx file.
