You may need to reinstall the programm that show that error: Some of it's files may be missing or been replaced by some older version that don't support the needed functionality.

That type of error means that a program has a problem starting because of lack of some code files(s) that it needs to run.
If you want an answer, you will need to expand your question. For example what are the "some files".
