Emclient 11 startup problem

Hello there, after upgrading to EmClient 11 on all pc at home (3 PC) they experience the same behaviour, at startup, if i open Em client nothing happen, i have to kill the process and start the client again, then after some time it shows the splash screen and start, it’s not fast is slow to start but after that it works all day with no problem.
Someone else have this problem?
I never had a single problem before on all my PC, in a lot of years, emclient worked perfectly.

Solution : It was the Antivirus that was in conflict, now it’s ok, never been a problem before with same antivirus ESET.

Thanks
Cheers

Windows 11 26H2 latest updated as 22/10/26
Emclient : 11.0.1267 (ca9fa42)

Suggest uninstalling - then reinstalling. For me, upgrading to 11 worked fine for a few days - and then today it appears eM was uninstalled. As in files were…just gone.

So I manually uninstalled, re-downloaded and installed 10 ( because 11 wouldn’t run for me) - and…

Now there’s complaints on startup about file versioning. I went to the data storage area, completely deleted the Archive folder, then in each of the other folders deleted the “folders.dat” file.

Started up - now it says an update is required. Allowed that to happen…

I’m functioning again. Since I keep all my emails server-side (and resent the fact the eM insists on downloading them all anyway) - having to freshly download doesn’t bother me. My settings appear still intact.

There may, and probably is, a faster way but this got me operational again. At least at the moment.

Thanks for the tip, i already tried to do a clean install but the problem is there in my case unfortunately.
