I tried to add Excel data source to my project and bind it to existing web test, but encountered an error during execution. The execution log states that there is no actual data, which is not true.
After discussing this with the support engineer, it seems that the issue is related to the Access DB driver. Test Studio works with the 32-bit version and the new Visual Studio 2022 works with the 64-bit version.
As a workaround I can use an older version of Visual Studio.
