If you want to correct these Path errors for those running wordpress on VPS or dedicated Web Server, I advice read the following which explains wher the problem comes from:
For MS IIS environment:
As far as I am concerned, I manged to adapt that on my web server environment (MS IIS 7.5), and I solved this by doing the following: adding the path to MySQL bin in open_basedir in php.ini
So what you have to do is to add a line at the end of your php.ini file containing the path to MySQL executables.
This line should look like this:
open_basedir ="C:\Program Files\MySQL\MySQL Server 5.5\bin" (replace this path with yours on your environment)
Warning: if you had already un comment the open_basedir value in php.ini, just add a semicolon after the initial value and paste the path to MySQL bin afterwards. Should look like this:
open_basedir ="InitialPath;Path to MySQL bin"
