Unable to load datamodule after update to 9.0.1

[cointec]

Hello,

After update delphi 10.4 to version 9.0.1, when I try to open the datamodule that has the component of connection on it, I get an exception

"Error creating form: Oracle provider is not registered. You should add the OracleUniProvider unit to the uses clauses of any unit in your project ..."

This is the uses of the datamodule

Code: Select all

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Db, ExtCtrls,  syncobjs,
  ActnList, DBClient, Variants, MemDS, DBAccess, Uni, InterBaseUniProvider, UniProvider, OracleUniProvider,

If I switch back to 8.3.2 all runs fine.
I have checked also 8.4.4 and all runs fine

Could you please clarify, if the UniDAC v. 8.4.4 and UniDAC v. 9.0.1, which you are using, have the same edition? How was UniDAC 9.0.1 installed? It was installed by using the installer or from source codes? Is the TOracleUniProvider component present in the IDE after installation?

[cointec]

9.0.1 raises the exception in Delphi 10.4
8.3.2 and 8.4.4 does not raise the exception in 10.4.

Not checked with other delphi versions.

Please, clarify, do you install UniDAC 9.0.1 from source codes or by using the installer?
In the first case, do you install all the providers you need? Are you able to create the simplest new project using OracleUniProvider and UniDAC 9.0.1?

[cointec]

I have intalled 9.0.1 with the installer over 8.3.2 ==> raises exception
I have reinstalled 9.0.1 ==> raises exception
I have reverted and installed 8.3.2 from installer over 9.0.1 ==> Ok
I have installed 8.4.4 from the installer over 8.3.2 ==> Ok

I don't use the source code to install the product.

Hope this helps
