Trying to re-install Em Client and get message Database check tool has detected an error - contact eM Client support and include error message - How ?
Close eM Client
Delete the eM Client folder located in C:\Users%windows user%\AppData\Roaming
Start eM Client
Then you need to set it up like when you first installed it, unless you have a backup available which you can restore using Menu > File > Restore
Magic - thanks for speedy response
