On an old computer, which I use to make tests, basecamp can't be installed. The double click on the downloaded file results in an error message "the application can't be started, configuration (Anwendungskonfiguration) not correct".
Data of the computer: Windows XP Home SP 3, Pentium 4 CPU 3.2 GHz, 1,00 GB RAM. NVidia Geforce FX 5700 VE, net framework installed, Windows mediaplayer 11 installed. Antivirus Program activ (the same as on my other computers, where basecamp is installed).
My suspicion: 1,00 GB RAM (with 1000 Bytes per kB) is not the same as 1 GB RAM (with 1024 Bytes per kB)
