Are you running K2 Setup through the network?

Please copy the K2 Setup files to the local machine first, for example in C:\Temp, and then UNBLOCK the file before extracting it, otherwise you will get the “Mark Of The Web” issue where Windows blocks sensitive files - more info here - https://www.thewindowsclub.com/fix-windows-blocked-access-file

Hi ​@Saqlain Supariwala have you resolved your error?

Hi Milla, we started a private conversation, but I think this issue would be better suited towards Nintex Support or perhaps Nintex Professional Services.

Thanks Christian!
