NetExtender install says another version is already installed but it isn't?
I am using a Windows 10 laptop. I had NetExtender 10.2.309 installed. I uninstalled version 10.2.309 from Settings - Apps. I tried to install 10.2.315 but it shows "Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel." I checked Apps again and Sonicwall NetExtender is not there. I ran the NxCleaner.exe program (as an Administrator). It could not find anything so it used the default location. Still failed. How do I install NetExtender?
