Mac Mccoy Posted February 12, 2022 Report Share Posted February 12, 2022 Hello Allain, I'm having similar issues. 1st Pro 11 reverted to trial mode; tried to reactivate by entering just the serial number but it wouldn't activate (-24 error as I recall); on the next try it automatically went to activate manually; supposedly, this is a no internet connection operation but it's not; it requires a logon to "nitropdf.com/activation" which doesn't work using the link; can get there by manually typing in the URL; once there I'm supposed to enter the ID number and serial, click submit (shows as "activate" to generate a text file for later use; regardless of how I enter it, I get "invalid data": I've gone through REVO Pro, Nitro cleanup tool, CCleaner scan, manually removing all "Nitro" related register entries, reinstalling Pro 11 and even Pro 126.96.36.1994 msi (had to get that from another download site because your link wouldn't work.); ALL installs automatically went to manual mode; from there I went in circles as described above. I have Pro 8, 10, 11, 12. Also, I downloaded version 188.8.131.524 exe from your update site. When I try to install, it starts with the download but errors out just before starting the install. Right now, I don't have any version installed and have cleaned everything I could find related to Nitro. I can send you the serial(s) in a private message if desired. I've not hair left! Help! Thank you. Mac ' Link to comment Share on other sites More sharing options...
