>Question: what is the safest way to do this? I don't want anything in the old, currently used system to be altered. I simply want to create a testing area for SDT and their app in VFP7. I want to run the Update() routine but am afraid it will update the vfp5 tables. How much of SDT do I need to put at the client site to accomplish this? When I validate the database in the new dir, it shows my changes (things that don't match) so I try to run update() but it looks for dbcxmgr.vcx. I only installed the updated dbc, dct, dcx, dbcxreg.*, sdtmeta,*, sdtuser.*. Don't want to install parts that aren't legal to install!

Only if you remove the code from the Methods field of all the records. Those classes should be included in your project and just compiled into the APP/EXE. I do not provide them separately, and, therefore, do not have to remove the code from the Methods field. This should only be done on a copy of those files as well. The compiled code is in the ObjCode field.

When you copied the app files, did you make a complete copy of all the files in the data folder? Or are you trying to let them run the VFP7 app against the same data as the VFP 5 app?
