Also, for the issue "could not be located in the dynamic link library WLXPhotoBase.dll", I would like suggest you re-register the file and check if it helps.
Click Start, Run and type in the following command:
regsvr32 \windows\system32\WLXPhotoBase.dll
To replace the WLXPhotoBase.dll file:
1. Close all open programs.
2. Click Start, point to Find, and then click Files or Folders.
3. In the Named box, type WLXPhotoBase.dll.
4. In the Look in box, click My Computer, and then click Find Now.
5. In the search results list, right-click WLXPhotoBase.dll, and then click Rename.
6. Type WLXPhotoBase.dll.old, and then press ENTER. If there are multiple copies of the WLXPhotoBase.dll file in the list, rename each copy.
Regards.
