Hello Everyone,
We recently upgraded our desktops to Windows 8.1 64bit from Windows 7. We use Oracle as database. Back in Windows 7 we had v13.0.1.220 of following packages: SAP Crystal Reports, version for Visual Studio 2010 - 32 bit & 64 bit runtime. And we had Oracle 12.
Now in our new computers we also have Visual Studio 2013, and same version of Oracle 12. In VS2010 When we try to open a connection with Oracle Provider for OLE DB:
And for the Microsoft OLE DB Provider for Oracle:
By the way, sorry for the non-english localization. Error window simply says:
"Unable to logon.
Details: ...
Source: ...
Description: ...
Local Error: 1019 [Database vendor code: 1019]"
We do have this problem in Visual Studio 2013 too. Falling back to W7 is not an option 
Because of this error we cannot update datasource (view etc.) in our reports.
Thanks in advance
