Hello Ryane Helder,
Thank you for posting in Q&A forum.
You can troubleshoot the issue as below.
1.Please check you can access the .msi file like \file server\share\file name.msi on client machines.
And you can create a group and put all the machines that need to apply Software Install GPO to these machines to this group and assign this group to have read permission on the shared folder above.
2.Because you assign a package via GPO, so you can create an OU and put all the machines that need to apply Software Install GPO to this OU and link the GPO (Computer Configuration*Software Settings**Software installation*) to this OU.
3.For some specific GPO, if we want to refresh them, we must sign out and sign in to make user configuration to take effect (folder redirection or drive map via GPO). We must restart the machine 1-2 time to make computer configuration to take effect (such as install software via GPO).
For these GPO above, if you only run gpupdate /force or wait for the 90-120 minutes to want to GPO refresh, it will not.
In your case, please restart the client machine 1-3 times and check if the software is installed in Control Panel on client machines.

I hope the information above is helpful.
