While launching the B1 Dashboards (this can also happen on our other products, and the troubleshooting steps are the same), you might end up with the error shown below:
This usually happens due to the lack of 32-bit HANA drivers or corruption in the machine you get the error from. To fix the issue, please install 32-bit HANA drivers (the same version as the 64-bit drivers) in the machine you get the error in.
HANA drivers need to be installed with "Run as administrator" -privileges.
Based on our investigation, it seems that SAP version 10 is able to run with only 64-bit drivers installed, but HANA itself requires the 32-bit drivers too. The problem can also occur if there's corruption in the 64-bit drivers, so if installing the 32-bit drivers doesn't fix the issue, try reinstalling the 64-bit drivers.
In order to check what version needs to be installed, check it from the HANA Studio:
Both the 32-bit and 64-bit drivers are available from the SAP download site:
