Unzipping this and running it without an install does not work on Win 7 32-bit OS. I've installed it at home on Win 10 64-bit OS and it works great. However, I do not have admin rights at work and in the past, I've had to unzip it and run it manually and it worked. I currently get the error message:

[Window Title]
...\cppcheck-1.70\cppcheckgui.exe

The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.

[OK]

[Bassam Abdul-Baki]

Thanks! That did the trick.

For NON-ADMIN Users:

Download the correct OS version executable instead of just downloading the default MSI executable.

Unzip somewhere and rename all DLLs to their right names. Rename "_" to "-" for the API DLLs and remove their GUI extensions to make them DLLs.

Move qwindows.dll to a folder named "platforms" right under root.

Running the GUI executable (after renaming) should tell you wish DLLs it hasn't found and need to be renamed. One DLL needs a hyphen in the name.

For bulk renaming, I use BRU (Bulk Renaming Utility).

On Windows 7 (64-bit), I found that after installing the Cppcheck 1.70 MSI, the Cppcheck.exe program would note start. A dialog box was displayed, saying the program can't start [...] msvcp140.dll

Install the Microsoft Visual C++ Redistributable for Visual Studio 2015 to fix this. https://www.microsoft.com/en-us/download/details.aspx?id=48145

Thanks! It should be installed automatically by the installer. If you're good at Wix feel free to take a look at our script and see if you can tell us why that did not work.

This is not a good place to report installation problems. Use the Cppcheck issue tracker instead: http://trac.cppcheck.net

For others, this appears to be the open ticket for this issue: http://trac.cppcheck.net/ticket/6980
