Invalid Signature?

With the latest upgrade I am getting the following message shortly after the upgrade begins: "iTunes and QuickTime has an invalid signature. It will not be installed". Never had this problem in the past while upgrading iTunes and QT. Does anyone know what the problem is? Is it possible to fix this? If so, How?
Thanks,
Lou

I don't know the answer to this one, but I wonder if you are using Apple software update?

If so it might be worth trying a manual update by downloading the iTunes installer:
