F-Secure product installation fails due to error: "F-Secure Hoster (Restricted) failed to start"

This discussion has a more recent version.

Issue:

  • PSB Computer Protection, PSB Server Protection, Client Security or Server Security installation fails.
  • Windows system event log shows error message: "Error 1920. Service 'F-Secure Hoster (Restricted)' (fsnethoster) failed to start. Verify that you have sufficient privileges to start system services." 

Resolution:

The error message might indicate that there are missing permissions in the root-directory where the F-Secure product is trying to be installed or is installed:

  • You will have to verify that the default permission set. If you are using the default installation path (C:\Program Files (x86)\F-Secure), verify that the Program Files (x86) directory has permissions set for the following: NT AUTHORITY\NETWORK SERVICE.
  • In doubt, reset the permission on that specific directory back to defaults and retry the installation.
Other possible solutions:
  • Check if Windows is fully updated
  • Check or reinstall .NET Framework 4.7.x
  • Check or reinstall Universal CRT
Potential Workaround:
  1. Rename following files to anything else (e.g. vcruntime140_old.dll):
  • On 64 bit Windows: 
    • C:\Windows\SysWOW64\vcruntime140.dll
    • C:\Windows\SysWOW64\msvcp140.dll
  • On 32 bit Windows:
    • C:\Windows\System32\vcruntime140.dll
    • C:\Windows\System32\msvcp140.dll
  1. ​​Restart the computer

If the steps above still causing error message "fsnethoster does not have sufficient privileges", there is a possibility that registry key HKEY_USERS\S-1-5-20 doesn't have the required permission for NETWORK SERVICE and fsnethoster is unable to create an entry there.

  1. Click Start
  2. Type regedit, and press Enter
  3. Navigate to and select registry key HKEY_USERS\S-1-5-20
  4. Select Edit
  5. Select Permissions
  6. Click Add...
  7. Type NETWORK SERVICE
  8. Click Check Names (the name should get underlined)
  9. Click OK
  10. Check Allow checkbox for Full Control (also Read permission should be automatically allowed)
