OSEng.dll Getting Quarantined by Anti-Virus
I downloaded this version (OSDSetupV1.4.5.exe) and tried to install it but right at the end of the installing process it says that it can’t run and Sophos (my anti-virus software) pops up with a Mal/RufTar-c virus and quarantines it. The file that is quarantined is called OSEng.dll and is located in OptiSurface folder.
OSEng.dll needs to communicate with our license server and that is why your antivirus software probably quarantined it. Please adjust your antivirus software to allow OSEng.dll access to the internet.
