I encounter the same problem with Visual C++ every now and then. I’m posting this to educate people who are facing the same problem.

The “R6034” error is a message from Visual C++ that appears when the application attempts to use the ‘at’ macro with the ‘*’ operator (as opposed to the ‘&’ operator) on a non-pointer type. The error indicates that the at operator with the ‘*’ operator is being used with a value of 0 or 0.0 as the first argument.

Every programmer faces one or more runtime errors from time to time, even experienced programmers. However, in this article, I will discuss a low-level problem that is not a bug but a design issue, and how to solve it.

We’ll look at what runtime error R6034 is, why it happens, and how to repair it on a Windows 10 computer in this article. There are certain apps in Windows 10 that need the proper loading of the “C runtime library.” You’ll receive a runtime error if there’s a discrepancy due to software or hardware problems.

In most instances, you have a defective application or out-of-date Microsoft Visual C++ redistributable packages installed on your machine. In your situation, just upgrading the aforementioned packages and uninstalling the most recent program installs would resolve the issue. If it doesn’t, you’re dealing with a complicated issue that necessitates sophisticated remedies like addressing hardware incompatibility problems, repairing damaged system files, or changing the registry.

  • Error with the hardware driver
