An important component of your software is the set of Machine Profiles used by the program to process designs for embroidery. Without this critical component, your software would not be able to output embroidery files.

On some occasions, certain aggressive utility programs running in the background have been known to erase or otherwise compromise the integrity of these files, causing error messages at the time of saving files from your embroidery software.

Knowing which utility program on your computer creates this scenario would give you the best chance to address the issue, either by "allowing" these specific files from your embroidery software or otherwise preventing such utility program from scanning or altering the Sierra folders where they are stored.

A temporary solution would also be to simply copy all the Machine Profile files to the folder where the program keeps them. This solution only works until the next time your utility program decides to erase these files again or somehow render them unusable.

To manually copy the Machine Profiles to the proper folder, simply extract all the MCH files contained in the ZIP file below to the following folder:

• C:\Documents and Settings\All Users\Application Data\Sierra\Common\Settings (XP)
• C:\ProgramData\Sierra\Common\Settings (Vista / Win7)

Note I: you may need to enable hidden files in order to view and access some of the above folders.

Note II: if you are experiencing a similar issue with Machine Code Interpreter files, repeat above steps as explained here.

Note III: follow this link if you need to manually register the DLL that controls the processing of stitch files.
