Reinstall gives: "A version of this software is already installed" error


Recommended Posts

Hi Support,

This issue started with the uninstall of a problematic Windows Update (KB4586878). I resolved the problem with the DNS, but then Emsisoft started giving problems. I uninstalled the software but an attempted reinstall gave the "A version of this software is already installed" error.

As per this article: https://help.emsisoft.com/en/1787/how-do-i-completely-uninstall-an-emsisoft-product/ I ran EmsiClean and attached the log.

Emsisoft version: 2020.12.1.10579.
Device details: Name: DESKTOP-SNF8BOK OS: Microsoft Windows 10 Pro 10.0.18363 (64-bit)
Laptop: Acer NC-E1-571G-32348

In the cloud console, the device is showing as offline. As a temporary measure, might it be possible to install a 30-day trial of Emsisoft as I only have Windows Defender installed at the moment?

Many thanks for your help!

 

Kind Regards,

Liam

Go ahead and allow Emsiclean to remove everything, and then restart your computer twice (sometimes a second restart is needed for everything to be removed). After that you should be able to reinstall.

The free trial is the exact same software, just with a different license, so it wouldn't install either.

Hi Arthur,

I ran EmsiClean and then after the first reboot I ran it again to see what it might show. I have attached the log.

However, I think that the message is a false positive as it came up again when I checked after the next reboot. At that stage I reinstalled Emsisoft successfully

Thanks for your help! You can close this ticket.

Kind Regards,

Liam

There were a couple of things left over (a driver and a service) that still needed to be removed. I don't think it would have been an issue though, unless they were from an older version of Emsisoft Anti-Malware. If updates had been installing fine, then you probably shouldn't have any trouble.
