floating-point support not loaded
The necessary floating-point library was not linked.
[!NOTE]
If you encounter this error message while running an app, the app was shut down because it has an internal problem. There are several possible reasons for this error, but often it’s caused by a defect in the app’s code, or by attempting to run an app that was not built for your particular computer processor.You can try these steps to fix this error:
- Use the Apps and Features or Programs and Features page in the Control Panel to repair or reinstall the program.
- Check Windows Update in the Control Panel for software updates.
- Check for an updated version of the app. Contact the app vendor if the problem persists.
Information for Programmers
This error can occur in your app when the floating-point library was not linked. Check for one of these causes:
-
A format string for a
printf_sorscanf_sfunction contained a floating-point format specification and the program did not contain any floating-point values or variables. To fix this issue, use a floating-point argument to correspond to the floating-point format specification, or perform a floating-point assignment elsewhere in the program. This causes floating-point support to be loaded. -
The compiler minimizes a program’s size by loading floating-point support only when necessary. The compiler cannot detect floating-point operations or floating-point format specifications in format strings, so it does not load the necessary floating-point routines. To fix this issue, use a floating-point format specification and supply a floating-point argument, or perform a floating-point assignment elsewhere in the program. This causes floating-point support to be loaded.
-
In a mixed-language program, a C library was specified before a FORTRAN library when the program was linked. Relink and specify the C library last.
Sometimes opening an app might give you a headache with Runtime Error Code R6002 – Floating Point Support Not Loaded in Windows 10. This error causes app crash issues and does not allow an app to load properly. Windows app will be closed automatically and then you will see the error message Visual C++ R6002 Runtime Error – Floating Point Support Not Loaded.

Summary
In this article, I tried to explain the 5 best methods to fix Microsoft Visual C++ Runtime Error R6002 in Windows 10 Machine. If you find this helpful, then please leave positive comments.
Sometimes we can unpack protected executables in Windows but there is a runtime error
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: ***.unp.exe
R6002
- floating point support not loaded
There is some info in UPX sources: https://github.com/upx/upx/blob/8d42b12117130b944023335cc2b76072c145db4d/src/p_w32pe.cpp#L200
// This works around a "protection" introduced in MSVCRT80, which
// works like this:
// When the compiler detects that it would link in some code from its
// C runtime library which references some data in a read only
// section then it compiles in a runtime check whether that data is
// still in a read only section by looking at the pe header of the
// file. If this check fails the runtime does "interesting" things
// like not running the floating point initialization code - the result
// is a R6002 runtime error.
// These supposed to be read only addresses are covered by the sections
// UPX0 & UPX1 in the compressed files, so we have to patch the PE header
// in the memory. And the page on which the PE header is stored is read
// only so we must make it rw, fix the flags (i.e. clear
// PEFL_WRITE of osection[x].flags), and make it ro again.

Some driver-related issues can be solved faster by using a dedicated tool. If you’re still having problems with your drivers, just download DriverFix and get it up and running in a few clicks. After that, let it take over and fix all of your errors in no time!
We have an application built with Visual C++ 2005, and one customer has reported that he’s getting this runtime error:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: [path to our application]
R6002
- floating point support not loaded
According to Microsoft (on this page), the possible reasons for this are:
- the machine does not have an FPU (not in this case: the customer has an Intel Core 2 Duo CPU and I haven’t seen a machine without FPU since the 486SX)
- printf or scanf is used with a floating-point format specification but there are no FP variables in the program (our app contains FP variables but I’m pretty sure we never use printf or scanf with FP formats)
- Something to do with FORTRAN (no FORTRAN code in our app)
Also, the error is occurring while they’re using our application (specifically, just after they select a file to be processed), not when the application starts up.
I realise this is a long shot, but has anyone seen anything like this anywhere before? Google was pretty unhelpful (there were lots of unsupported claims that it was a symptom of some kind of virus infection but very little apart from that).
Any suggestions gratefully received

Are you linking a static version of the CRT? If so, you need to have floating point variables in the binary that calls printf(). And these variables have to be really used (i.e not optimized out by the comppiler).
Another possibility is a race between the CRT initialization and the code that uses these FP routines, but that would be hard to produce.

R6002 can be caused by printf trying to print a string that contains a percent-sign.
Most likely root cause of such printf failure is a program that manipulates arbitrary files and prints their names. Amazing to me, there really ARE people who put percent-signs in file names! (Yes, I realize that is technically legal.)

printf(«%fn», (float)rand() / RAND_MAX);
I experienced the same runtime error in a program compiled with VS2010 command line cl.
The reported error occurred without the (float) cast and disappeared when I added it.
