AnyConnect Software not installed on Windows 10

Question

Hello Team,

We tried to upgrade Anyconnect secure mobility client 4.9.00086 through the SCCM tool on the end-user machines. Some of the users having issues after the upgrade. they are getting below error message.

"There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." error message while installing the latest AnyConnect Client applications on user PCs.

This issue has occurred on Windows 10 1607 (OS Build 14393.3930) version. On this OS we can not install a higher version anyconnect file and a lower version anyconnect file.

Some of the user's are sitting in offices and some of the users are working from home through VPN.

When we deploy package through SCCM that time user connected on VPN and at that time existing VPN get uninstall & communication of that systems with SCCM get disconnected so that new version up-gradation is gets stuck till when it again communicate to SCCM. After communicating with SCCM then also it's not working.

We have tried the below troubleshooting steps.

> The customer has followed the steps as per the article https://www.petenetlive.com/KB/Article/0000985. After that tried to install the AnyConnect 4.9.00086 version again, but we were still getting the same error message.
> Shared PurgeNotifyObjects.exe file with the customer and ran the command "PurgeNotifyObjects.exe -confirmdelete". After that tried to install the AnyConnect 4.9.00086 version again, but we were still getting the same error message.
> Also tried to run the Microsoft trouble-shooter tool https://support.microsoft.com/en-us/help/17588/windows-fix-problems-that-block-programs-being-installed-or-removed
> Tried to install different versions of AnyConnect Client 4.9.01095 and 4.8.03052, the installation has failed with the same error message.

On the same OS version, the same Anyconnect version is successfully installed on the end-user machine.

Can you please suggest the next step to resolve this issue? It's really helpful for me.

Thanks,
Ashwin

Hello,
Try Anyconnect install with parametr for logging.
msiexec /package anyconnect-win-%version%-core-vpn-predeploy-k9.msi /norestart /passive /l*v %temp%\anyconnect-win-%version%-core-vpn-predeploy-k9.log

There is an msi 1603 error at the end of the file. - https://learn.microsoft.com/en-us/troubleshoot/windows-server/application-management/msi-installation-error-1603

MSI (c) (48:24) [12:46:20:514]: MainEngineThread is returning 1603

It could be detected previous installation of AnyConnect.
But there is an error in the middle of the log file.

MSI (s) (D0:78) [12:46:18:193]: Product: Cisco AnyConnect Secure Mobility Client -- Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action VACon64_ndis6_Install, location: c:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\VACon64.exe, command: -install "c:\Program Files (x86)\Cisco\Cisco AnyConnect Secure Mobility Client\vpnva-6.inf" VPNVA

You need to discuss with Cisco experts. This could be a file locked by an antivirus or other application.

check if u have the file C:\Windows\System32\acnamfdbctl.dll if not copy it to this location from C:\Windows\System32\DriverStore\FileRepository\acnamfd.inf_amd64_250208eb024e44a8 try to reinstall Anyconnect. Good luck. Note: in case u will install the client for VPN user u will need to kill the VPN connection first in the batch file using: taskkill /t /f /im vpnagent.exe
