Close Videopad. Using Windows Explorer (file manager), delete all files in these folders...
"C:\Program Files (x86)\NCH Software\Components"
"C:\Users\<account name>\AppData\Roaming\NCH Software\Components"
Now reinstall Videopad.
If still no success, please share a file or two that has the issue. Someone will check it out. Upload the file/s to a free server, such as Google Drive or MS OneDrive, get a shared (public) link, copy the link and paste it here or to me in a Private Message via the mail envelope in the top-right corner of this forum. When using Google Drive, if necessary change "restricted" to "anyone with link can view."
