In two cases yesterday, I installed this service pack after disabling Norton on one site and AVG on the other. I did not update the sample data and in both cases, we couldn't open the Financial Reporter. Message said it couldn't open the FR. In both cases, I had to download the most recent full product, in which case the install process said it was not the correct update and had to enter a previous S/N and Install Code. After the install was completed, everything worked fine. Something very strange about the service pack.
