Have you tried googling this error code and checking a couple of the suggestions from the search results?
There is a possibility that cod4x was installed incorrectly, or the antivirus program blocked the executable file.
Two easiest ways to get 1.7 are:
Disk version of Cod4 (may need to install patches 1.6 and 1.7)
Steam version of Cod4 and downgrading to 1.7 (see download channel in Cod4x Discord)
If you are already on 1.7 then you do not need to install these patches.
Your error message is somewhat generic from what I see on google. Try installing the Latest Microsoft Visual C++ Redistributable Version
If that does not help, google your error code, there are a lot of threads with potential solutions for this.
