This article relates to the following Windows error message:

A sharing violation occurred while accessing [file-name]

If you see this error message, it is probable that it is caused by one of the two following scenarios.

Possible Cause 1: A file is being used by another application

According to Microsoft, this error can be caused by multiple applications running a file simultaneously.


  1. Create a duplicate of the Scan2CAD directory which is in your Program Files
  2. Ensure the directory is named anything different to the original, for example ‘Scan2CAD v9 copy’
  3. Launch the Scan2CAD .exe located in the duplicate directory.

Possible Cause 2: Anti virus software.

It is possible that your anti virus software is being over zealous.


Ensure any Scan2CAD.exe task is allowed by your anti virus software. You may also choose to ‘pause’ the software.
