Hello

It seems that there are some traces in the registry left even after uninstalling the program.
I suggest that you follow these steps to delete the registry keys related to Cisco AnyConnect.

Disclaimer: The steps below includes system registry modification. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection,
back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Make sure to backup registry first, please refer to this support article:
How to back up the registry in Windows. Please follow the steps below:

1. Press Windows key + R. The run dialog box will open.

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
