I don't know how to do it. I recently crashed mongobat8 and had a trial period of only a few days. I uninstalled it and installed it again. I found that it could not be activated. After several times, I even used up the trial period, it's very depressing..
So I found some posts on the Internet to solve the problem and sorted them out...
Solution:
1,DeleteC:/Documents and Settings/all users/Application Data/FlexNET/adobe_00080000_tsf.data);
2. Start Adobe Acrobat 8. On the reactivate page, click "Other activation options ";
3. Select "Activate by phone ";
4. Run the Adobe Acrobat 8 Registration machine (this installation disk contains drops), copy the activation code to the registration machine, and press "Activate" to obtain the authorization code;
5. enter a new authorization code on the software interface and press "Activate ".
In this case, the problem will be solved...
