When I click "About" it brings up a box but it doesn't show the serial number.All it says is registered to: my email address. I installed from the Pro Content not as a standalone product.
I've now downloaded and installed SP3. The end result is the same thing happened.It went through the install and then the Invalid Serial Number box popped up.
When I closed out of all of them the remaining box said the install had succeeded.
Even though that is the case I can no longer find WinDvd on my system.The icon is gone and when I do a search on WinDVD all it finds is the SP3 .exe file.
I tried to go in and uninstall and start over but WinDVD is not found by either Revo Pro or Win10 System uninstall feature.It's just gone.
Sorry,forgot to mention I have Windows 10 Fall Creator Update applied and all updates installed available as of this morning.
I will try and contact someone about this.
