As I mentioned, to install I have to go offline and run the adobe.preactivate.dmg file. Then I run the adobe,xi.ml.dmg file and I click on the "License this Software" button I get into the serial number activation section. Because there is no internet connection Serial NUmber Validation cannot occur and on the screen appears the massage "Having trouble connecting to the Internet". Then we select the Offline activation button and click the "Generate Request Code" button. AT this point things are confusing. You can either run the adobe.postactivation.dmg file and then go online on the same computer an receive using the Request Code an REsponse Code with which you can activate the program. Alternatively, you can go into another computer online and get the Response Code to activate the program. The main issue is that the website www.Adobe.com/go/getactivated from which you can get the Response code is not responding.
I have now done so. The program was installed without asking me the serial number. After a while, I received a message to add my serial number which I did, however, I got a message saying that the serial number could not be validated.
Many thanks. I will try it and I will report back to you. Unfortunately this will not happen today as I have family obligations. I will try tomorrow. Is this OK?
