MS Office rendered inoperable by uninstalling Crystal Reports .msi

I am using Crystal Report XI R2 SP5 and Visual Studio 2005. I use the CrystalReports11_5_NET_2005.msm in my setup package, which produces an msi file that is about 83 MB in size. I am creating a small application that runs our .rpt files, using the .NET API.

I have been testing the install package on a number of user machines. In the past, I have chosen the 'For Everyone' option on the install dialog that let's you choose between 'For Everyone' or 'Just for Me.' Recently, I decided to just leave the default, which is 'Just for Me.' That's when our trouble began. After uninstalling the application, we discovered that MS Office would no longer work.

Has anyone had a similar experence?

I would like to set the default for the install to 'For Everyone,' but I have yet to find any documentation that tells me how to do that. I can remove the radio buttons for the dialog and I can install via the command line, but neither of these options tells me whether the 'For Everyone' or 'Just for Me' option is being used.

Can anyone shed light on that question?

Thanks.
