This occurred when trying to move through the text of the update radio buttons in browse mode in the normal Adobe Flash installer:

error executing script: <bound method MSHTML.script_moveByLine_back of <virtualBuffers.MSHTML.MSHTML object at 0x03F647B0>> with gesture u'up arrow'

COMError: (-2147352570, 'Unknown name.', (None, None, None, 0, None))

This is on a pretty clean install of Windows XP sp3 with no further updates applied.

It seems that hasAttribute was only implemented in IE 8. Ug. I'll have to try getAttribute. Otherwise, we might just forget about supporting isFocusable properly in IE 6.

I've seen this or a very similar error in IE8 intermittently for some time. I'm not sure if a ticket was done, but if it was its going to be a long time back.
IE6 is more or less unusable now in any case.

Closing, as the original post discusses the flash installer, which development will be discontinued in 2020, Windows XP, and Internet Explorer 8, which is outdated now.
