Class not registered when trying to install apps or even InstallShield update from installshield app ikernel.exe

We have an XP Home laptop that is having a problem with the error message 'class not registered' for several pieces of hardware that want to install their software - Iomega externa USB CD drive and Canon printer, and others that slip my mind right now.

When trying to install the Iomega apps, I get an error with ikernel.exe 'class not registered'.  Googling that, it's an InstallShield app.  Their website has suggestions of clean the temp folders, reboot, tweak DCOM settings, etc.  all were empty, configured correctly already, but the problem persists.  I found an INstallsheidl page saying to delete the engine folder and reinstall installsheild... even that gets the 'class not registered' message!

The machine runs OK other than when trying to install apps.  We are logged on as an administrator, there are no other users logged in or even that exist...

This seems like a general issue with classes / installshield which is why I posted it here.

Other than a reinstall, any recommendations!?

This is NOT the right TA for this question.

Disconnect the hardware from the laptop. Go to Start menu -> Control Panel -> Add/Remove Programs and remove the software for the devices that aren't working.

Reinstall the software for one of the devices.
Reconnect the device when either instructed to do so, or when the installer has finished installing.

It's a problem with ikernel in general - it first showed up with hardware, but then we noticed that any new installs were failing with the same message.  even at installshield's website, they tell you to do a reinstall of the installshield engine,.... and that fails!

So when I searched for keyworkds here, this came up as one of the most common sites for the 'class not registered' error...
