Compatibility: Version 6.7.x and 6.8.x

When compiling and merging with 4D Engine the following error occurs:



There are a couple of reasons as to why this error may occur:

#1 - One or more actual 4D Engine files are corrupted or missing, in which case reinstalling 4D Engine would solve the issue.

#2 - The less obvious reason for this error occurring is if 4D Engine is trying to overwrite an existing executable file and is unable to overwrite this file. One reason this can happen is if the executable file is in read-only mode, and you grab an existing project which points to this read-only file.
