Please follow the steps given below.
Install SDK files from lenvica.in/downloads
It contains three files namely sdk files, one auto install file and auto uninstall file.
First copy all files in sdk folder and paste it in windows/system32 folder.
If it asks for replacement then run the auto-uninstall process in the downloaded files and then freshly install the files by running auto install.
