transferring eM Client from old to new computer

I have been trying to import my database from an old computer (eMClient 7.2) to a new Windows 11 computer (eMClient version 10.2) but have run into the following error message:

ICSharpCode.SharpZipLib.Zip.ZipException: CRC mismatch
at ICSharpCode.SharpZipLib.Zip.ZipInputStream.CompleteCloseEntry(Boolean testCrc)
at ICSharpCode.SharpZipLib.Zip.ZipInputStream.BodyRead(Byte buffer, Int32 offset, Int32 count)

at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e)
at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)

What am I doing wrong? I would appreciate some guidance. Thank you.

Hey @webtiger

To move your eMC data etc to a new computer

The best way to move all your data etc is through: Backup & Restore.

Follow these steps:

On the old device:

1./ Create a backup: Menu ->Backup
2./ Deactivate the license on this device: Menu ->Help ->License
3./ Find the .ZIP backup file and move it to your new device (with a USB)
The default location is ..\Documents\eM Client)

On your new device:

1./ Install eMC (www.emclient.com/dist/latest/setup.msi)
2./Move the ZIP backup file to: …\Documents\eM Client (create the eM Client folder if it is not there)
3./ Having installed eMC skip initial setup
4./ Restore from your backup through Menu ->File ->Restore
5./ This will transfer everything to mirror your previous installation
6./ Activate your license in Menu ->Help ->License
