Problem Solved

In search for the solution for my problem I tried to install the client from the command prompt with elevated rights from c:\temp where I located the .msi installation file:
msiexec /fv anyconnect-win-4.1.04011-pre-deploy-k9.msi /lvx “c:\Temp\ac-Uninstall.log.txt”
Again the installations failed. This time with te message: The file “ManifestTool.exe” is not marked for installation.
Only option I had was to click on “Ok”.
This time the log “c:\Temp\ac-Uninstall.log.txt” was created. In this log I found this line:
MSI (s) (E8:40) [07:42:34:275]: Product: Cisco AnyConnect Secure Mobility Client — Error 2753. The File ‘ManifestTool.exe’ is not marked for installation.

I searched on the internet for “error 2753” AND “is not marked for installation”. I found this site that directed me to the solution:
https://helpdesk.illinoisstate.edu/kb/1962/Error_Error_2753_The_File_is_not_marked_for_installation_when_installing_Cisco_Jabber/

In the registry I found the key that was causing the installation failure. I deleted the key in the following steps and after that I succesfully installed the new client.

To edit the registry, do the following:
1.Click Start and type regedit in the box.
2.A dialogue box will pop up with the following text: Do you want to allow the following program to make changes to this computer? Click Yes.
3.Browse to the following location: HKEY_CLASSES_ROOT\Installer\Products\
4.Within the Products folder, locate and delete the registry key which contains product information for Cisco AnyConnect Secure Mobility Client.
◦Each registry key within Products is an alphanumeric string. Select the first key and look on the right side for ProductName REG_SZ Cisco AnyConnect Secure Mobility Client. Go through each key in the Products folder until you find the one for Cisco AnyConnect Secure Mobility Client.
◦In my (this) case: [HKEY_CLASSES_ROOT\Installer\Products\E8CB28D0EF413434EBCBFF65361793A3]
◦Your version of Cisco AnyConnect Secure Mobility Client might have a different name for this registry key.
◦I recommend making a backup of this registry key before deleting it.
5.Close the registry editor.

After this start the installation of the new Cisco AnyConnect Secure Mobility Client.
