What does the error “invalid activation response” mean when I try to activate off-line?
If you are activating off-line and you receive this error it is most likely that the activation request file does not correspond to the machine being activated or that the request file you sent via e-mail was altered by your e-mail client. The activation request file you send in must be generated by the machine that is to run the activated compiler. The request file contains information specific to the Windows installation on the machine and is only valid for that machine. You should regenerate the activation request file any time you need to reactive to ensure that the data it contains is accurate. If you sent the contents of the file in the body of an e-mail message and you have set your e-mail client to send in HTML format, this would explain the error. The activation program is expecting plain text for any received requests. If you send the request file as an attachment, this will work around this issue. Also check no unusual end-of-line characters could be sent in the request file
