I have installed a cs5 version. But when it opens, it always asking new serial number...?. How I solve this problem...?
Contact the supplier who sold it to you.
If you haven't lawfully purchased it, you won't find any help on cracking it here.
looks like you havent purchased your version, contact adobe.com, you can also download a trial version from their website
Thanks guys for your information....!. How is the cost for a c55 licenced version.?

The retail price is $700. If you're upgrading from an older legal version, it's $300. If you're a student, you can get it with a student discount for $200.
There is also Photoshop Elements, which is only $100 retail.
