After installing, some files are missing (w3btrv7.dll)

[Customer Service]

Installation appears to install but C21 tells me there are files missing. (w3btrv7.dll)

1. Check your C:/Program Files(x86) folder for any references to Pervasive.
2. If you see none, you should install Pervasive from the latest C21 CD by browsing the CD (as opposed to letting the Auto Run guide you).
3. On the CD you’ll find a PVSW folder. Look for the installation file there and right-click on the icon.
4. From the right-click window, select “Run as Administrator” and follow the instructions on your screen.
