Need help installing ODAC 122011x64 so I can connect ADW to Power BI
I figured out the solution after reviewing this post. Apparently having over 2TB of free space on a hard drive causes this problem. You have to go into command prompt and create a temporary file to get your free space under 2TBs using something like this:
fsutil file createnew temp_1TB_file 1200000000000

Run the setup.exe again and then delete the temp file after.
Update: After doing all this I still was running into the same issues in Power BI. Then I read the troubleshooting notes from this page more closely and realized that I might have found the problem when it said:
If you downloaded Power BI Desktop from the Microsoft Store, you might be unable to connect to Oracle databases because of an Oracle driver issue. 

I uninstalled the PowerBI Desktop that I had installed from Microsoft Store and installed it from the download from its website and tried connecting to Oracle ADW again through PowerBI and IT WORKED!!! So much troubleshooting but it finally works!
