Cannot install BM Design Desktop Video Program

I am trying to install the BM Design Desktop Video Program but it always fails
"there is a problem with the Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." is the error message I get.
I have tried installing version 14.4 and 10.4.3 with no luck. I have also installed all redistrubutables and started the windows installer service manually.
When investigating the error in "event viewer" I found this error message:
"Product: Blackmagic Desktop Video -- Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action RegisterBMDCodecLib32Action, location: C:\Program Files (x86)\Blackmagic Design\Blackmagic Desktop Video\, command: regsvr32 /s BMDCodecLib.dll"
I really need this to work so any help would be appreciated.
