This was an error I got while trying to have a new ADOxx installation.

After consulting with the ADOxx team, specifically Wilfrid, this is the quoted cause and sollution:

The error message means that there is a mis-match between your non-unicode settings and the database collation used.

The non-unicode setting, as you mentioned in your email,  needs to be the same as the instance collation used for ADOxx.
There are 2 options to fix that problem:

a) Adapt the non-unicode settings to collation:Please have a look at the collation of the database instance. By default, ADOxx creates a new instance called ADOXX15EN with collaction "Latin1_General_CS_AS". In the PCs control panel, you can switch from Greek to a Latin codepage (e.g. English), performt the required restart and re-run the installation. The drawback of this approach is that ADOxx won't store Greek characters properly.

b) Remove current instance installation and create a new instance ADOXX15EN with Greek collation:Alternatively, and in case you want to be able to enter Greek characters properly, please remove the instance ADOXX15EN using the "Remove  software"  functionality in the Control panel. After removal has completed, setup a database instance with Greek collation manually using ADOXX15EN as an instance name (detailled steps are available here:http://www.adoxx.org/live/installation-guide-15-other-collation) and re-run the ADOxx installation.


This, in combination with the advice I got from Nikolaos Tantouris to restore registry entries, fixed my problem.
After installing/uninstalling multiple databases, the registry entries can get mixed up. There are many ways to fix the registry, Nikolaos suggested the tools from 
http://www.tweaking.com/
which worked perfectly.


This is just to document the error for future reference. 
Best regards,
Orestis
