@SpaceMarshall Hi. Welcome to the forum. This has been asked plenty in the forum recently and in the past. This is a variant of the MSVCP140.dll that happened for Windows 7 users. Basically it’s a windows error due to the lack of specific components. Usually these are obtained through Windows updates, however Pencil2D bundles an installer in case you don’t have them.
We have a troubleshooting section in the download page below the program direct links. Here’s a direct link to that section Download | Pencil2D Animation where you can find details on how to solve this and other tech issues.
Please go to the Pencil2D folder and run the vc_redist.exe installer.
If you have issues with this installer then please read this reply and download the installer directly from Microsoft:
