Photoshop returns MMXCore, pdfl50.dll, or msvcrt10.dll error (CS on Windows)

Issue

Adobe Photoshop starts very slowly, pauses, crashes when loading plug-ins, or returns one of the following errors during startup:

– “Could not load the MMXCore (fastcore) routines module because is it not compatible with this version of Photoshop.”

– “pdfl50.dll could not be found”

– “msvcrt10.dll was not found, reinstalling might solve the problem.”

Solution: Remove Photoshop 7.x or third-party plug-ins from the Photoshop CS/Plug-ins folder.

To remove plug-ins:

1. Remove all Photoshop 7.x and third-party plug-ins designed for Photoshop 7.x from the Photoshop CS/Plug-Ins folder.

2. If you’ve set the Photoshop 7.x plug-ins folder as an additional plug-ins folder in Photoshop CS, choose Edit > Preferences > Plug-Ins & Scratch Disks and do one of the following:

– Deselect Additional Plug-Ins Folder.

– Click Choose and select a folder that doesn’t contain Photoshop 7.x plug-ins and third-party plug-ins designed for Photoshop 7.x.

Background information

Photoshop 7.x plug-ins and third-party plug-ins designed for Photoshop 7.x are incompatible with Photoshop CS.
