Big problems installing BMD Desktop

This has been going on for some time now on one of my Windows 7 machines.

When I run the Desktop Video Installer v10.10 (and previous versions) I get this....



(What the Blackmagic Camera Utility has got to do with the desktop drivers is beyond me!)
So I go into the control panel to remove the "Blackmagic Camera Utility"...



.. and it starts to INSTAL the camera utility, or at least 'configure' it. Doesn't "remove" mean... 'r e m o v e'?



So now heres the WEIRD thing.... after a few minutes of green progress lines going from left to right, the green line then starts going RIGHT to LEFT!!! which would mean it is undoing every thing it just did?!?

I am mainly a MAC guy so maybe this is more of Bill Gates wizardry but after it completes what ever it was doing the "Blackmagic Camera Utility" is still installed and I can not instal Desktop Video Installer.

Please, can someone explain the logic behind all of this? (and yes, firewalls are disabled)

restart in safemode and try again. More of a windows problem than a BM problem.

Tried that, same result. thanks.

The risk of not doing a reboot every time a software install/de-install happens is that sometimes "in-use" drivers don't get replaces/removed.
Try going into Device Manager and look for any camera devices and delete them if they exist. I sometimes have to do this with Decklink cards if they don't get firmware updates.
Maybe the USB driver for UltraStudio range has something in common with the cameras.
