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 :
- Open a control panel and manually uninstall the Universal printer.
- 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
