I'am not customer - I try to see trial but get this problem.

Hmm, if you're an evaluator and still evaluating a software some months beyound its trial expiration period, does it mean that you're using a "slightly modified" (more known as a cracked) version? Would it explain why you're getting this problem while all others do not?

Dmitri, I am not using a "slightly modified" version. I've downloaded phpdock 1.5 about two months ago but have not enough time to test then.
Some days ago I decide to test it, install, get this error and post here. I get this error from the first start phpdock after installation.
You wrote that actual version is 2. I've downloading new trial, install and have the same error.

And I have Zend Platform installed on my PC. maybe is this critical?
