What are PCS Diag.exe Error Messages?

PCS Diag.exe Runtime Errors

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

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

Some of the most common PCS Diag.exe errors include:

PCS Diag.exe - Bad Image.

Finding the source of the PCS Diag.exe error is key to properly resolving these errors. Although most of these EXE errors affecting PCS Diag.exe will happen during startup, occasionally you will encounter a runtime error while using Sony Ericsson PC Suite 6.011. This can occur due to poor programming on behalf of Sony Mobile Communications, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of PCS Diag.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection.
