Symptoms¶

You are getting the following error in Runner/Server Log or as a separate dialog:

---------------------------
Microsoft Visual C++ Runtime Library
---------------------------
Runtime Error!

Program: C:\Users\User\squish_bin\squish-3.4.4-qt45x-win32-msvc9\..\squish-3.4.4...

R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.

---------------------------
OK
---------------------------

Cause #1 - Application is statically linked to Qt¶

Solution:

Use a dynamically linked application.

Cause #2 - Different compiler used for Qt and Squish¶

Solution:

Use the same compiler for the application and for Squish, or use a correctly matching Squish binary package.

Cause #3 - Different build type used for application and Squish¶

Solution:

Use the same build type for application and for Squish, or, with Squish binary packages, use a release build of the application. (Binary packages provided by froglogic are release builds unless otherwise stated.)

⚠️ Remember that the compiler, Qt, Squish, and AUT build types (and Qt versions) must all match up. If one is built as a debug type, they must all be.

⚠️ The Squish binary packages are not compatible with debug builds of the AUT. Please use a release build of your AUT for testing or build Squish from a source package (you need to specify the option --enable-debug for Squish's configure program).

⚠️ MinGW compiles applications of debug type by default.

Cause #4 - Stray MSVC runtime DLL files¶

One or more of the following files is...

• in the working directory of the application,

• in one of the directories listed in the PATH environment variable, or

• in <SQUISH_DIR>\bin or <SQUISH_DIR>\lib:

Possibly stray MS Visual C++ runtime files:

• msvcr80.dll
• msvcm80.dll
• msvcp80.dll
• msvcr90.dll
• msvcm90.dll
• msvcp90.dll

ℹ️ Please note that in order not to be considered "stray" files, a file such as Microsoft.VC80.CRT.manifest or Microsoft.VC90.CRT.manifest must exist in the same folder as the above files.

Solution:

Remove or rename these files, or move them out of the PATH.

ℹ️ Please note: This should be safe to do because these files (without the above mentioned manifest file) present an invalid configuration as far as Microsoft/Windows are concerned.

Cause #5 - Application .exe not linking against respective MSVC runtime¶

Using the Visual C/C++ compilers it is possible (by not using the /MD compiler/linker switch) to link .exe files without directly linking against the respective MS Visual C++ runtime.

Here is an example of a .exe file compiled with MSVC9, but not linking directly against the MSVC9 runtime, shown in Dependency Walker :

The problem arises when the application tries to load a DLL which requires that or another version of the MS Visual C++ runtime, but which does not specify this in its manifest (or which simply does not have a manifest).
