Many things can cause missing Action functions (like corrupted SMS WMI and network account issues), but…something that may be overlooked is network meter. That’s right, a metered connection will often render unusual, anomalous results with the Software Center and CM agent, depending on how you have the agent configured for users.

You’ll notice, the Client Actions will not update (however, the C:\Windows\ccmsetup\logs\ccmsetup.log will say successfully installed):

 

Checking logs in the C:\Windows\CCM\Logs folder, you’ll see warnings and errors referring to metered network:

 

The fix is to disable metering on the current network connection (which will often be a wireless connection).

Restart computer or the ccmexec service. Monitor the Actions using the CM applet in Control Panel, or navigate to C:\Windows\CCM\Logs and watch logs appear.

Notes

Metered connection settings are stored here

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\DefaultMediaCost

Value 1 = not metered
Value 2 = metered

I came across this error when trying to upgrade from El Capitan to Sierra (setting up a very specific dev environment). Method 1 resolved my issue.

Method 1 (dual authentication issue)
Download something from the app store (a small app) and authenticate.
Try downloading the larger app/OS file now.

Method 2 (date issue)
Command + R at Mac startup to enter Recovery Mode
Utilities > Terminal

date mmddHHMMyy (Pacific Time)
csrutil enable
csrutil clear

Reboot and try downloading the larger app/OS file now.

Method 3 (privilege issue)
Change permission for the Users Shared folder

sudo -s
cd /Users
ls -al
rm Shared
mkdir Shared
chown root Shared
chgrp staff Shared
chmod 775 Shared

Try downloading the larger app/OS file now.

Slack 3.4.1 – May 3, 2019

Bug Fixes

We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.

Slack 3.4.0 – April 18, 2019

Bug Fixes

Interactions with network drives are now handled with grace and panache. Or, at the very least, “better”.

If you want to launch slack minimized, you now can. We will no longer stand in your way.
We’ve changed the look, feel and texture of our new HTML notifications. Give them a try! They’re delicious.

Sometimes on Windows 10, moving the window, say, up would cause a white bar to appear. We raised the bar.

Also, moving the window would sometimes change the size of the window. Your aim was true; we no longer move the goalposts on you.

In the Apps and Features and Uninstall a Program window, the icon showing up was not the right one. It now is.

The notification and unread indicators on the taskbar are now more readable.
Blurry icons were an issue for some users with multiple displays. Now all is clear.

The Slack icon, previously appearing with an opaque background color on Windows 10 is now all the clearer for being less clear.

Some people were seeing sidebar icons for teams other than the one they were in. This was confusing, and has now stopped.

And finally, if you have been having issues with keyboard or cursor issues, you should no longer be having them.
