First posted in the comments section, I'm including information as answer, as it worked for the user.

Here is a link useful to solve the blank spaces trouble: https://www.vbforums.com/showthread.php?703121-RESOLVED-How-to-Shell-from-a-directory-with-spaces-in-path

For non-english characters, please try with the following approach: Illegal characters in path (Chinese characters)

If the last solution does not work, another alternative is to loop through files in directory and identify the one you are looking for by another meta-data ou file info. In this case, please check this link: vb.net how to loop through a directory listing?
