Fujitsu PFU We purchased a very expensive software from them (rack 2 filer, 5.0) and lost the product key. We called them, and they told us that they couldn't give us a product key, even though we had just purcha Sunnyvale, California

Sounds like you are the one who has no reading comprehension, or not very many brain cells, for that matter.  The original poster said "the product key was nowhere to be found."  In the version of English that I speak, that means he did not receive the serial number.  Even if he did receive it and misplaced it, there is no reason not to tell him what it is.  If you had a functioning brain, you would realize that this does not, in any way, enable you to install and activate more than one copy of the product.

No Josh, I'm not retarded. You can't read.

To the commenter above: are you retarded?  A license key does not stop you from installing the software on multiple computers.

If you paid for and never received a license key for the software, you should sue them for breach of contract.  Before you do that, try doing a chargeback with your credit card company.  There is absolutely no reason why that company should not give you your license key.

Why didn't you enter the product key when you installed the software? If they supplied you with another product key it would be the same as giving away a copy of the software because it could then be activated on a second computer. That product key is their protection against unauthorized use.
