Hello, getting this error message

by Rycleve1 / May 11, 2012 4:01 PM PDT

I am getting this error message when trying to install a video drive on a desktop. I am running XP Pro and SP3.

Error: Setup failed to launch installation engine: Class Not Registered

Then it just stop with the installation.

Another error I am receiving is a box popping up saying only administrators can install these files and the problem with this is I am logged in as admin. I even created another account and made that admin with the same error problems. Also hit ctrl + alt+ del and signed in as admin with the same problem?

Thanks in advance for any help.

What app is this?
by R. Proffitt Forum moderator / May 12, 2012 2:06 AM PDT

I read "Video Drive" but that may have been "driver" but details are missing. This could happen on say some ATI card where you don't have .NET 2.0 installed but no mention of ATI video cards.

Try this, tell more. All the details.

If it is video drive
by MarkFlax Forum moderator / May 12, 2012 5:35 AM PDT

then I pass,

But if you mean video card driver, then why are you attempting to install this driver? What problems are there?

The last time, the 'only' time, I had to install a video card driver was when I was replacing a dead video card. The new one was a different make so I had to uninstall that card through the Device Manager, shut down the computer, replace the video card, boot up the system, then install the driver for that new card.

Is that what you are trying to do?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
