The procedure used to upgrading to a new level of Tadds depends on the type of changes in the new release as compared to your existing code and
database level. These procedures are described in the online Tadds Help documentation and can be located by starting Tadds, pressing the F1 key, searching for Migration
. However, use the following tables to determine the specific procedure to use:
If you are updating a Tadds SingleUser, HomeClone or Demo system:
1. Start your current Tadds system and do a Data Export (to floppy diskette or other device).
2. Install the new level of Tadds on your system.
3. Start the updated Tadds system and do a Data Import (of the floppy diskette or device).
4. That's it. You are done.
If you are updating a Tadds SiteLicense system, check the following table to find the type
of update you will be doing.
If it says to do a "TableDefinitionsChanged" update:
0. Prep work: Download the correct SETUPLi.EXE file from this site. Make sure you are
logged onto Windows using the User's actual logon ID and password. Make sure the user
has local administrator authority on the PC being used. Check that the user has full read /
write / modify authority on the Tadds_BE shared LAN folder.
1. Make sure that no one else is using (connected to) the Backend database. (There is a
button on the Tadds Utilities panel to help you do this).
2. Make a backup copy of your entire TADDS_BE folder and tuck it away someplace safe
where it won't get lost. (A USB flash drive is nice for this.) Call it something obvious like
TADDS_BE_SAV1. (This is for insurance in case something bad (power drop?) occurs
during the update process.)
3. Do the same for your Tadds_FE folder that is on your C: drive. Call it \Tadds_FE_SAV1
4. Start your current Tadds system and do a Data Export (to hard disk or USB flash drive).
5. Now run the SETUPLi.EXE file that you downloaded from this site. It may issue a few
security grumble messages you will need to approve or enable.
6. Now store a copy of your SETUPLi.exe file in your Tadds_BE LAN folder, appending its
level number to its name (example: SETUPLi_150705.exe) so you will have the right
level of SETUPLi.exe when you need it in the future to instsall new Tadds FE users.
7. Now start your Tadds Front End application by double-clicking on its desktop icon. Tadds
will start but (since it is still at the old level of Tadds) will tell you that it is down-level and
will proceed to shutdown so it can do a self-update. After the self-update completes, start
Tadds_FE again. Note: Each time you start it, Tadds will warn you that your Tadds license
will expire in 5 days. Ignore these warnings. The next step fixes things.
8. Now use the Tadds IMPORT utility function to load the BackEnd tables with the user-data
that we set aside in step 4, above.
9. At this point you are done. All the other Tadds FrontEnd client PC's will do a self-update
the next time (their) Tadds_FE application is started.
