Today I attempted to install the official ICQ messenger for Mac (which I downloaded here: http://download.icq.com/download/mac/en ) but the installation of the .air file failed and asked me to contact the software creator for a new installation file.
Recommended system requirements:
- Mac OS X v10.4.9 or later (ok)
- Flash 10 and above (ok)
- Adobe Air 2.5 (ok)
The system.log shows the following error:

So it's quite obvious that the package signature failed. However, I was able to install this messenger on another machine successfully, so I'm wondering why it always fails for this MacBook.
