Retrieves the version of a file.
OutputVar := FileGetVersion(Filename)
The name of the variable in which to store the version number/string.
The name of the target file. If a full path is not specified, this function uses the search sequence specified by the system LoadLibrary function. If omitted, the current file of the innermost enclosing File-Loop will be used instead.
ErrorLevel is set to 1 if there was a problem or 0 otherwise.
A_LastError is set to the result of the operating system's GetLastError() function.
Most non-executable files (and even some EXEs) won't have a version, and thus OutputVar will be blank in these cases.
