Re: How do I transfer Acrobat 9 Standard from on PC to another? I have the serial and key for the initially installed software. It was installed from download and I have NO CD.

Since you have the orignal Acrobat 9 standard serial no., You can download Acrobat 9 standard setup using the following Link and install it : https://helpx.adobe.com/acrobat/kb/acrobat-8-9-product-downloads.html

Once it is installed, you can use the license key to activate it and use it.
