Terminal Service Plus

Follow these steps :

1- Make sure no users are connected and delete these two folders if present : C:\Program Files (86)\TSPlus and C:\wsession
2- Download and install the latest setup : dl-files.com/Setup-TSplus.exe
3- Reboot.
4- Uninstall using unins000.exe located in C:\Program Files (x86)\TSplus

I recommended you also to deactivate your antivirus before installing TSPlus.
If your antivirus is too intrusive you can set an exclusion rule on the following path : C:\Program Files (86)\TSPlus and C:\wsession

Thanks for your response.

Unfortunately, none of those solutions worked for me, and I ultimately had to reformat/reinstall the server.
