Dear dongxi,
Thank you for your reply.
I recommend to try to uninstall Video Splitter from your computer at first (you can use Start -> All programs -> Solveig Multimedia -> SolveigMM Video Splitter Home Edition -> Uninstall or using Windows Control Panel).
After uninstall please make sure that all files in the folders below were removed from your computer
"C:\Program Files\Solveig Multimedia\SolveigMM Video Splitter Home Edition"
and
"C:\Program Files\Common Files\Solveig Multimedia"
and
"C:\Program Files(x86)\Solveig Multimedia\SolveigMM Video Splitter Home Edition"
and
"C:\Program Files(x86)\Common Files\Solveig Multimedia"
If there will be any files in this folders please delete them manually from these folders.
Then you could install the product again.
Please use the link below to download the latest version:
