@jpsdr: The Tesseract version used by SE is now "Tesseract 4.0 beta 3" which might need a newer "Visual C++ Redistributable for Visual Studio" - could you try to install this:

Does that help?
The reason for upgrading from Tesseract 3.02 to 4 is mainly due to support for more languages... Tesseract 4 is a lot slower and it's also the reason for the SE increase size (4 extra mb)!
@varekai:The sluggish behavior is when doing what exactly? Did you change video player?
