The SHFOLDER.DLL error likely occurs due to corrupted or missing Windows registry. As an initial troubleshooting SHFOLDER.DLL needs to be registered on your system. To do this, we recommend that you follow these steps:

  Click Start, type command, right-click on it, then select Run as administrator.
  Type these commands one after another:
  regsvr32 /u SHFOLDER.DLL, then press Enter. This will un-register the file.
  regsvr32 /i SHFOLDER.DLL, then press Enter. This will register the file.
  Once done, close the Command Prompt.
  Restart the program that you are trying to run.
