Error 1722 Installing Anyconnect VPN (Windows 7)

Question

Hi,
i'm trying to install Anyconnect VPN Client (anyconnect-win-2.5.2006-web-deploy-k9) to connect the university wifi, but i always get an error 1722
There
is a problem with this Windows Installer package. Ein Programm, das als
Teil des Setups ausgeführt wird, wurde nicht wie erwartet beendet.
Contact your support personnel or package vendor.
I had this error and i couldn't fix it and i reinstalled the Windows 7 (HP Compaq 610). Than i could install the AnyconnectVPN. Today it tried to update, than i get the same error. Now i can't use it and i can't install it.
There are a lot of people with this problem but there is no information in internet to fix this problem.
I really need help. I don't want to reinstall the windows. (It's also not a solution).
There is a  key (Standart) HKEY_LOCAL_MACHINE/SOFTWARE/..../RUNONCE without a value.
What should i do now?

Answer 1

Have you uploaded the AnyConnect package to the vpn gateway yet? I would recommend that you uploaded the latest version: AnyConnect version 2.5.2017.
Firstly you would need to upload the package to the vpn gateway, and you would need to use the following:
anyconnect-win-2.5.2017-k9.pkg
Once you have uploaded the package to the vpn gateway, you can download and install the AnyConnect onto your Windows 7 in 2 ways:
1) From Windows 7, assuming that the vpn gateway has been configured for AnyConnect, then you can browse to the vpn gateway ip address, and the AnyConnect software will be automatically downloaded and installed on the Windows 7 machine.
2) Alternatively, you can also pre-install the AnyConnect using the following file:
anyconnect-win-2.5.2017-pre-deploy-k9.msi
Hope that helps.
