'Now scroll down until you see the jDownloads ones.
There are a total of 15 tables, the seven regular jD3.9 tables and eight 'backup' tables from the previous jD 3.2 version.
In this example the backup tables have '_backup_3_2_69' appended to the names. This indicates that the update was from a jD3.2.69 version.
At a later stage we will be re-naming the 'backup' tables

You will see that in jDownloads only the backup tables remain, which is what we need.
The next step will be to rename the tables.
In this next stage we will be renaming each of the tables by deleting the '_backup_3_2_69' from the name. Of course if you upgraded from an earlier version it will show that version number. Please note you must be at jD3.2.69 or higher to upgrade to the 3.9 series.
This renaming is carried out one table at a time.

Select one of the tables that contains the _backup in the name
Now at the top of the display check you have selected the correct table.
Then click on Operations.
On the next display scroll down to Table Options.
The only thing that will be changed is the table name.
Now edit the name to remove the '_backup_3_2_69' part.
This can be a bit 'fiddly' as often the screen is quite compact.
On a desktop or laptop one can use the CNTRL key and the mouse wheel to enlarge the screen.

Install jDownloads 3.2.69
Select _Extensions Mamage Install
Then choose 'Upload Packager File' and drag the jD3.2.69 zip file onto the upload area.
After a short while you will see a report like the one opposite.
This indicates that the renamed database tables were found.
We now have to repeat the installation exactly as before.
Whilst the report above says Joomla! will treat the second install as an Update do not use the Update button - Use the Install as shown opposite.
Again after a short delay you will see that the installation has completed.
Scroll down the screen and then click on the 'Start jDownloads Now' link.
We are nearly done!
It is possible that whist the jD3.9 version was being used you might have added or deleted some Categories and Downloads.
So got to the jDownloads Control Panel and click on the 'Check Download area now' link as indicaterd opposite.
This will give a report similar to the one shown opposite dependant upon whether some Categories and Downloads were added or deleted.
Check Third Party Extensions
Following the upgade to jD3.9 series you may also have updated the plugins for the standard supported extensions.
If you had done this then clearly they need setting back to the 3.2 versions
The Special Extensions for JComments, Komento and Community Builder may be found at jD3.2 extensions. The plugin support for Alta User Points is effectively 'built in' to jDownloads but it does need installing as described in the Alta User Points article.
For JComments please see the article Enabling comments on Downloads with JComments
For Komento see the jD3.9 article on Komento .
For Community Builder see Using Community Builder.
Note that version 6 and above of Acymailing supports both jD3.2 and jD 3.9 .
