Finding the serial number for the downloadable Photoshop CS5

[siriwhaaa]

I installed and opened up Photoshop on my laptop, but it's asking me for a serial number, and I can't find it. It's not on the page where it says Download Adobe Creative Suite 5 products, either. Any suggestions?

When you originally purchased CS5 is when you would have received your serial number

If the software was installed and activated previously you might be able to acquire the serial number from it using one of the following...

If it's a Windows machine then try running Belarc Advisor
