So PDF995 is showing up in the Control Panel, but Band-in-a-Box doesn't see it? It seems like it's partially installed then. At least part of it must be on your computer, which may be blocking reinstallations from working.

I'd try running CCleaner, and see if it still shows up in the Programs and Features list after that. This could just be a registry issue, and this could fix it.

Thanks
