The REVO uninstaller method is more extensive than the standard Windows uninstall.
Yet another route you might pursue. Close Videopad. Using Windows Explorer (the file manager), delete all files in these folders. Then reinstall VP.
"C:\Users\<PC Name>\AppData\Roaming\NCH Software\Components"
"C:\Program Files (x86)\NCH Software\Components" (or the path without the x86)
The best way to track this down is to share the project, so someone can analyze it. Please follow the steps below and we'll check it out.
Back up --- With your project on the timeline, click on MENU at the top-left. Click FILE|BACK UP PROJECT FILES TO FOLDER. Choose a folder and SELECT FOLDER.
Upload --- Use a free server - Google Drive, MS OneDrive, etc.* - to upload the saved, numbered FOLDER. Do NOT upload the individual VPJ or export file.
Get link --- Get a public link. Right-click the file and click SHARE. When using Google Drive, if necessary change "restricted" to "anyone with the link can view"
Share --- Click COPY LINK | DONE. Paste that link here, or click the folder at the top-right of this forum to message it privately to me. It won't be shared.
* Before uploading, right-click the folder, click PROPERTIES. Look at the File Size to confirm that it's not too big for the free space on the server.
