I have been trying to install Zend server all evening. I have tried installing after Flashbuilder for PHP, before, restarting, uninstalling, reinstalling. Done every possible combination. Tried installing off files given at Adobe Max, and off files downloading. Nothing works.
Every possible combination and I still get the error.. Error: -1622 Error opening installation log file. Verify that the specified log file location exists and that you can write to it.
I attached the screen shot.
