A file is missing or no longer exists. Most of the time, this is caused by antiviruses. We can put the file back in place for you, but if the cause is in the antivirus, you will need to add an exclusion in it to allow the correction.
Tip: You should ask your IT support to add the C:\\EstimateurNDCD folder to the antivirus exclusions. If you are computer savvy, you can always do it yourself. Once done, contact us so we can fix the missing or damaged files.
