Programme won't run after update 8.0

 After receiving an email inviting me to upgrade to 8.0, Copernic no longer runs. The symbol loads, system plug-ins start to load then it closes.

Running on a Window 10 machine with Microsoft 365.

I also have the same problem.

It *may* be related to the version of the .net framework you're running.  You may want to check that.

I'm completely untechnical. What is the .net framework? Thanks!

did you uninstall version 7 before installing version 8 by the way

Tbh I don't think so. I just got a message from the Helpdesk saying I should uninstall everything and start from scratch. 

The Helpdesk got back to me and told me to uncheck the box asking to keep config and index during uninstalling, then to reinstall again.

It now loads and is in the process of doing the very lengthy indexing of my files. It may take a day or two.

 Samne: After receiving an email inviting me to upgrade to 8.0, Copernic no longer runs. The symbol loads, system plug-ins start to load then it closes.

Helpdesk told me to uninstall all previous versions completely without keeping config and index then reinstall Copernic Desktop Search from scratch.

Now it's working fine.

I have this problem too


Dennis, make sure you have current windows 10 updates which will make ensure you have netframework 4.8, then you need to uninstall the old version completely, do not keep index and config files. It then ran ok on my desktop and index 3.4 million emails in 9 days . It crashed once, i restarted and it picked up where it had been and kept going. working good now.

I may have responded on the wrong version issue. This is a server version. I was checking the server and coppernic notifications said there was an update. So I allowed the update and now coppernic does not start. I have tried to uninstall and reinstall. The program starts and just closes. even if I remove the previous settings and profile. I looked for a download for a previous version but could not find it.  Any help would be appreciated. After removing the settings and reinstalling the setup wizard starts and then I get and error but it closes so fast that I can not seem to see the entire error. report. 

This is server 2008 r2. I just installed net framework 4.8 and rebooting the server. I double checked and the coppernic requirements say the OS is supported. 


Looks like installing dot net 4.8 may have fixed the issue. 


I discovered there are 3 ways to uninstal a program in Windows 10.  One works (because it has an option that allows you to delete config and index, which you need to do) and the other two don't work for this problem beacuse, it seems to me, they dont have that option.  One is: (a) in the folder where the program is stored (eg, C:\Program Files\Copernic\DesktopSearch) click on the uninstall.exe; this worked; the others are (b) using Apps & Features in settings (didn't work); and (c) using Control Panel\Programs\Programs and Features (didn't work).
