I am redoing my computer and reinstalling CS 6 Design & Web Premium. The installation would not complete, and when I ran it again, twice it gave me the error message, "The product you are trying to install is not Adobe Genuine Software and appears to be counterfeit."
The disk is mine and I have used it to install on this very same computer before. How can I get around this?
Step 1:
Navigate to Applications . Utilities.
If present Trash folder named " Adobe Application Manager" .
Step 2 :
Then click on below link and download Adobe Application Manager and install the same. :"
http://download.adobe.com/pub/adobe/creativesuite/cc/mac/ApplicationManager9.0_all.dmg
Once the installation process is completed , the installation box will disappear, then open Application folder and locate Adobe Application Manager launch icon and double click on it .
It will start update process and gets updated to Creative Cloud . No need to sign in, when it is launched,
Step 3)
If you are using installation disc , please copy the disc contents to computer and then start installation process.
