older version of OpenVPN Connect cannot be removed

[roydoherty]

I have removed a previous version of OpenVPN connect from a Windows 10 PC and I am trying to install v2.6. However there seems to some memory of the previous version laying around and it is preventing the new install.

I get the following errors:
"The feature you are trying to use is on a network resource that is unavailable" Click OK to try again or enter an alternative path to a folder containing the installation package openvpn-connect2.5.0.136_signed.msi.

When I cancel out of that it says "The older version of OpenVPN Connect cannot be removed. Contact your technical support group.

I removed the old version cleanly (or so I thought) using Programs and Features. There is probably something stuck in the registry somewhere, but I can't find it.

Any suggestions?

Thanks
