Hi there - whenever I try and install a version of Barracuda VPN software on this machine it keeps rolling back.  It still seems to think it has traces of an older version 3.3 on there.  The registry and program files are clear of anything related to Barracuda, VPN, cuda_sfilter, phion using a combination of revo uninstaller and searching the registry... but still won't install.  

The Secure Personal Access Client still shows under Ethernet Properties but is disabled/unticked but if I try and uninstall I get an error "Could not uninstall the Secure Personal Access Client feature. Secure Personal Access Client is still required by the following feature(s) and cannot be uninstalled until those features are uninstalled: Barracuda Network Access Client 3.3 x64


When I try and install the client the Windows log shows the following:


g the inf 'C:\WINDOWS\system32\DRVSTORE\spac_1A60BAD0325D1AED1AA7576131EB94A0FCE6B96F\spac.inf'. Unable to install network component 'cuda_sfilter_4.0.2.39'

Needless to say there is no C:\program Files\Barracuda folder

Anybody get any bright ideas or seen anything similar?

Similar issue - spent hours troubleshooting no network connectivity until I disabled this component and now it will not uninstall even though I re-installed the older client (3.6) and hotfixes and uninstalled again.
