I dont think all the jeys you have in RunOnce are from IE6 only.
Does IE6 really uses MSI ? I never have seen it.
Not that the "InstMsi1" and "InstMsi2" show that you made TWO tries to
install the MSI service.

Dont forget to clean your RunOnce Entries between installations.

And the

> "InnoSetupRegFile.0000000001"="C:\\WINDOWS\\is-K6KCV.exe /REG"
dont come with IE6

We only need to check if the first filename given is a readable
Then do the appropriate. And you can see that the only executable that
seems to be called is rundll32.exe.
The only thing that we know nothing about is the "Flags" key.
