The DocBundle tool won't launch, or the bundle generation fails
Problem:
The DocBundle tool temporarily stores the files needed to generate a package in the Windows Temp folder.
Sometimes certain files are not deleted at the end of the generation process, and these files can prevent future batches from being generated.
Solution:
The solution is simple: just clear the Windows temporary folder.
Start by closing as many applications as possible to free up as much write-locked file space as possible. Next, open the Windows temporary files folder. To find this folder on your computer, go to Start, Run, and then type: %temp%
All you have to do now is select all the files using the Ctrl+A shortcut, then press the Delete key on your keyboard.
P.S.: There will always be some files in this folder that cannot be deleted; just ignore them.
