i have a 64bit windows7 and i want to run a 64bit executable which is not inside the c:\Program Files\ directory. i always get the error:

The application has failed to start because its side-by-side configuration is incorrect.

i think this is because the OS treats it as 32bit although it is 64bit.

how can i still run this executable?

some more information would be cool, have you written the programm by yourself? I had a similar error once with a programm written in vs2005. – Aug 31 '10 at 14:21

This is likely not an issue of the application not residing in the \Program Files\ folder, but is actually a missing library. Windows can detect whether the executable is 32-bit or 64-bit regardless of where the application is in the folder structure.

I see this error often when the Microsoft Visual C++ Runtime has not been installed correctly. Where did this application come from? I would suggest contacting the original developer for support. You may also try downloading the latest version of the runtime from Microsoft to see if that fixes the problem.

If you copied the exe from c:\programe files\, then you have to copy all other files and folders within the same folder. After that you may run it if you are lucky.
