The following error will occur when a file that needs to be overwritten is still in use by another application or process:
Most commonly, this happens if you have an Image-Line product, using these files, open at some point prior to running an installer. In this case the application has not closed correctly, and the Operating System locks them as in use, in the background.
Fix this problem by either:
1. Restarting your computer and then install the application
2. Open the Windows Task Manager (Ctrl + Shift + Esc) and close all Image-Line related processes that are still visible in the list.
