Maybe those with issues have to do what we do with streamfab sometimes.
Get HiBit Uninstaller and uninstall and have it scan for leftovers and remove them.
Then reboot computer and download the latest installer at:
https://www.dvdfab.cn/mlink/download.php?g=DVDFab_x64
Revo uninstaller is said to work at times also. Both are available for free.

I have v13058 on my computer open and closed it several times and it has not asked me to update.
I also tried the update option in the program and it says I have v13058, you are up to date.
BTW: I never ever had to run an installer as admin for any dvdfab product including streamfab or dvdfab.
I tried once with streamfab and seemed to make things worse, also I am already admin on my PC why would I need to then run as admin on an installer.
And John Leach i would recommend getting rid of Norton, look for another anti-virus, just not Kaspersky..
Maybe Bitdefender, ESET, OR Malwarebytes, Malwarebytes is my person favorite, or even AVG or Avast.
