Follow these steps :

 

Delete the C:\wsession and C:\Program Files (x86)\TSplus folder and try again.

 

download this uninstaller first : dl-files.com/Uninst.exe and dl-files.com/Uninst.bin, make sure that these programs are downloaded in the same folder, execute it and reboot.

 

If this does not work then follow this procedure :


  1. Open a control panel and manually uninstall the Universal printer. 
  2. Make sure no users are connected, then uninstall TSplus, reboot your computer.


 

If these steps did not work then download and install a fresh setup before restarting above procedure : https://dl-files.com/Setup-TSplus.exe

 

I recommended you also to deactivate your antivirus before installing/uninstalling TSPlus
