What are MailClient.exe Error Messages?


MailClient.exe Runtime Errors

Runtime errors are eM Client errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when MailClient.exe is attempted to be loaded either when eM Client is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using eM Client.

In most cases, MailClient.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these MailClient.exe error messages mean that eM Client was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, eM Client will be unable to start without resolving these errors.

Some of the most common MailClient.exe errors include:

  • MailClient.exe - Bad Image.
  • MailClient.exe Application Error.
  • MailClient.exe could not be found.
  • MailClient.exe could not be installed.
  • MailClient.exe could not be launched. Class not registered.
  • MailClient.exe could not be started.
  • MailClient.exe failed to initialize properly.
  • MailClient.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
  • MailClient.exe is not a valid Win32 application.
  • MailClient.exe is not running.
  • Cannot find MailClient.exe.
  • Error starting program: MailClient.exe.
  • Faulting Application Path: MailClient.exe.

System Error


The program can’t start because MailClient.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the MailClient.exe error is key to properly resolving these errors. Although most of these EXE errors affecting MailClient.exe will happen during startup, occasionally you will encounter a runtime error while using eM Client. This can occur due to poor programming on behalf of eM Client s.r.o., conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of MailClient.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve MailClient.exe problems.

Download MailClient.exe Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying MailClient.exe to your appropriate Windows system directory. eM Client typically does not release eM Client EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing MailClient.exe and all other EXE files for eM Client. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
