Diagnosis

 

Looking at the error log you will see error message below:

If you look at the log, you can see the error is directly related to the FIPS cryptographic algorithms. According to Wikipedia, FIPS stands for Federal Information Processing Standards and it is a “standard developed by the United States federal government for use in computer systems by non-military government agencies and government contractors”.

 

As of right now, “Unhandled Exception occurred” error will be thrown in the R Tool if FIPS compliance is turned on .

  

Solution

 

Our Development team is fully aware of the problem with the FIPS compliance and is planning to sort this out in the future releases. As for temporary solution, you can consider turning off the FIPS compliance, of course after checking and making sure your IT manager is okay with it, and this should resolve the “Unhandled Exception occurred” error.

 

Here’s how you can turn off FIPS compliance:
