I've downloaded oracle 21c on my personal laptop. Check system compatibility (alls good). However, towards the end Im getting an error stating "Oracle Services for microsoft transaction server failed".

I am attempting to create a Sql Server Analysis Services Tabular Model and am having trouble accessing an Oracle database for importing data. I am using the following:
OS
-Windows 10 Enterprise (I am administrator of machine)
Tools to create tabluar cube:
-Visual Studio Community 2022 (64 bit) - Current Version 17.2.5
-SQL Server Analysis Services 15.0.2000.5 - Developer Edition (installed on localhost, services running)
Oracle database:
Oracle Database 21c Enterprise Edition Release 21.0.0.0.0 Production Version 21.3.0.0.0 - Developer Edition (installed on localhost), up and running and able to connect with other tools (e.g. Toad, Sqlplus, SqlDeveloper, cx_python, etc..)
I have a 64-Bit System Data Source Name created for ODBC connections, using Oracle Instant Client. This data source works just fine with other tools mentioned in the Oracle databse section above.
When creating a SSAS tabular model in Visual Studio and attemping to import a data source, I try the following:
Models
-TabularProject (my project)
-Data Sources > New Data Source > Oracle Database
At this point I get the following message:
Oracle Database
The recommended provider ('Oracle.DataAccess.Client') is not installed. You can continue with your current provider, however, it has been deprecated and may not work correctly.
and I click 'OK'.
From here, I enter the connection string of my locally hosted oracle database (localhost:1521/MY_DB.
When prompted for credentials, I select 'Database' and then enter the correct username/password to connect to my locally hosted oracle database.
Then I receive an error stating:
Unable to connect
We encountered an error while trying to connect.
Details: "An error happened while reading data from the provider: 'Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.'"
I've also tried the following method:
Models
-TabularProject (my project)
-Data Sources > New Data Source > ODBC
Then I choose my ODBC datasource for my locally hosted database (which seems to work fine for other apps) and I receive the following error:
Unable to connect
We encountered an error while trying to connect.
Details: "ODBC: ERROR [IM014] The specified DSN contains an architecture mismatch between the Driver (64-bit) and Application (32-bit)"
I have installed various Oracle Drivers including:
-64-bit ODAC: ODAC122010Xcopy_x64.zip
-64-bit instantclient basic: instantclient-basic-windows.x64-21.6.0.0.0dbru.zip
-64-bit instantclient odbc: instantclient-odbc-windows.x64-21.6.0.0.0dbru.zip
-64-bit instantclient sqlplus: instantclient-sqlplus-windows.x64-21.6.0.0.0dbru.zip
I have also tried these same steps for a remote hosted Oracle database (using both ezconnect string and a ODBC DSN) and even though the connections work just fine with other apps, it doesn't work with SSAS for some reason.
Any and all insight advice to get my SSAS tabular model connected to Oracle databases would be very much appreciated.
EDIT:
I have tried following a solution from this similar question and create a dsn, suffixed with _64, using only the 64-bit ODBC manager, yet I get the same results when trying to use that DSN with SSAS.
I have also tried the following steps, per Microsoft:
From https://learn.microsoft.com/en-us/sql/reporting-services/report-data/oracle-connection-type-ssrs?view=sql-server-ver16#64-bit-and-32-bit-drivers-for-power-bi-desktop:
2. Register ODP.NET Unmanaged Client to GAC:
C:\Oracle\odp.net\bin\4\OraProvCfg.exe /action:gac /providerpath:C:\Oracle\odp.net\bin\4\Oracle.DataAccess.dll
3. Add ODP.NET Unmanaged Client entries to machine.config:
C:\Oracle\odp.net\bin\4\OraProvCfg.exe /action:config /force /product:odp /frameworkversion:v4.0.30319 /providerpath:C:\Oracle\odp.net\bin\4\Oracle.DataAccess.dll
Yet, I still receive all errors shown above.
When my colleague attempts to connect he is having no issues. We both have previously been granted access to the server, and have established this is not an issue as my colleague can access the server on my Desktop though I cannot access the server on his desktop. (We both could up until recently when we had had to renew the server connection passwords).
We are both operating off 64-bit, Windows 10 desktops with the same Java version and are both using Oracle SQL Developer 19.2.1.247.
When I go to about properties and compare both in excel we see no differences.
We're quite confused why this is happening.
I am new to SSIS and ETL .I have a task to connect to oracle database from SSIS. But when I am giving source as OLEDB source and select Microsoft OLEDB provider for Oracle along with server name and credentials, it throws me an error on testing the connection. i.e.
"Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation.
Provider is unable to function until these components are installed."
I have seen many posts and blogs but I could not follow the steps and where I followed I could not connect. Hence I request you to please guide me in achieving the same.
You need to install Oracle Client on the server that holds your SQL Server database. Oracle Client is free of charge.
what is the purpose of Oracle Services for Microsoft Transaction server, I am asking this because I tried installing ODTwithODAC (Oracle) on a server and i got the error message Oracle Services for Microsoft Transaction Server Failed
I'm getting an error from report:
The OLE DB provider "MSDASQL" for linked server "linkname" reported an error. The provider reported an unexpected catastrophic failure.
I'm checking to find out the installed driver and port number from the Windows server 2008 R2. I checked in "C:\Windows\System32\drivers\etc" services file, but unable to get which exact service I need to check?
My ODBC data source administrator window is listing below drivers:
1. MySQL ODBC driver
2. Oracle in OraClient 10g
3. SQL Server
4. SQL Server native client
How can I find the detailed information; what is the current driver installed on what port number ? Is the current driver installed is compatible with Progress DB ? If it's not compatible, which latest driver I need to install to make it compatible with Progress 11?
You will need to download the SQL Client Access software from Progress web site.

Look for the SQL Client Access:
