MailClient.exe Bad Image

When start program got error, that I can’t simply close (it re-open again). It say that C:\windows\system32\atl.dll is not intended to run in windows. 
Is there any ways to solve this issue? 

Hi Victor,
unfortunately this is not enough information about the error to suggest any fix for you.
Could you please copy the whole error message next time and copy it here?

when I open app I got this issue. When I try to press Ok it appears again. Program doesn’t load. This error blocking launch. What another information I can provide for you? Is there any logs in your client?

Hi Victor,
something must have corrupted the file mentioned in the error message. This is not a pop-up generated by eM Client, but your system. I suggest running the eM Client installation file again and using it to uninstall eM Client.
After it does, try running a system check and anti-virus if you have one to check for any malware that could be overwriting your files. Restart your computer too.
Then install eM Client again and see if the issue persists.

Olivia
