dll not installing

Hello.

I have this weird problem.
when installing my basic msi all the files installed correclty.

BUT, when i'm doing upgrade from previous version I have 2 dll's that are not installed!
I tried everything I know (not much..) starting from reentering the files to the installtion package to messing up with the upgrades section.
the verbos log also did not yield any error. all the files including those two looks like they installed correctly.

I'll be glad if someone have any ideas about what I did wrong..

thanks!
