Unable to reinstall client integration tools after V4 Free Edition

After moving to V4 Free Edition, which is fast becoming a pain as I have to now go around 50+ servers and remove the client integration tools and install them again (you'd think not hey?) I am coming across the following error on a number of machines:

"Unsintall your client or Intergration service properly and restart your client machine." (Please note the spelling is as per the error in Vembu, a spell check may be needed by the devs)

I came across this article in the KB...

https://www.vembu.com/support/knowled...

Sadly, this doesn't help in the slightest. I have uninstalled, rebooted, searched for anything Vembu related, deleted, rebooted, screamed at it, rebooted, pulled my hair out, rebooted, rebooted, rebooted, and still I cannot install the new client tools.

Can anyone shed any light on this? What is being left behind on these servers to stop the installation? I have not touched the registry as yet, just in case I break stuff too much and can never use Vembu on these servers in the future.

With thanks,

EDIT: The KB article linked above has been updated to include detailed information on removing the client agent and tools to clean up the failed uninstall.

Thanks for pointing out the spelling mistake. We will correct it in our upcoming minor update.

To uninstall the Vembu Integration Service, you can log in to the Hyper-V host machine and uninstall the VIS from ‘Uninstall a program’ window. This will remove the VIS from the Hyper-V host.

However, If you could see this error after the uninstallation, I think there might be a few entries were not properly removed from the Hyper-V host machine.

So, to resolve this issue, log in to the Hyper-V host machine and check whether the Vembu Integration Service is listed in either the registry or services.msc. If it is listed, you can remove it manually by following the steps given below,

To remove the service, open command prompt with administrator privilege and run 'SC DELETE VembuIntegrationService'

Open the registry and check for the registry value for 'HKLM\SOFTWARE\Vembu\VembuIntegrationService' and delete it manually.

Then add the Hyper-V host from the BDR backup server.

Thanks for your reply.

Firstly, this is not a Hyper-V host, and I have made no mention of it being one.

The service uninstalled fine first time around that wasn't the issue. I have removed all Vembu entries from the registry (there were three entries regarding installation paths), rebooted again, and it has made no difference, I still cannot install the client integration tools.

I'd appreciate some kind of solution to this as v4 has now totally messed up all my backups. It is incredibly frustrating that I am having to uninstall the services and reboot servers as it is, without these further issues.

ANSWER:

After a conversation with Vembu support (thanks for calling me today) we have successfully removed the drivers that failed to be removed during the agent uninstall procedure. Once these were removed and the server rebooted I was able to reinstall the v4.0 agent via the VembuBDR as normal.

Thank you for your help!
