SolidWorks Thumbnails Graphics Do Not Display

Hi, Everyone

I have SolidWorks 2014

And I can't see any thumbnails Graphics Display in my folders of Windows 7

I try all the help in a few post but I can't see them.

1. I mark the Option Show thumbnail graphics in Windows Explorer“ - Nothing Happend

2. I attach the way my icons looks like

3. I do this step regsvr32 sldwinshellextu.dll -

4. Runing the regsvr32 sldwinshellextu.dll - Appears this error "0x80070005" and icons still the same

5. Also when i Open Solid Appers this error - Could not load SolidWorks DLL: GdtAnalysisSupport.dll

* Do you suggest to install the product again?

Can someone please help

Thanks a lot.
