Install the software from the CD or setup program that was supplied initially.
Start the software and register as normal. Close the software.
Copy the models: copy all the folders under C:\VCF8_old\Models to C:\VCF8\Models
In C:\VCF8_old\Data there are 3 files that are called Model, namely model.dbf, model.fpt, model.cdx. Copy these three files into C:\VCF8\Data.
Start the software.
Open a model and get to the map.
Run the option: Check shared tables. It is under the Utilities menu, under Technical utilities.
