Could not install JBuilder

[cema]

Tried to install JBuilder, Foundation version, on a Windows 2003 Server. Installation crashed with the following message:

java.lang.StringIndexOutOfBoundsException: String index out of range: -95

What am I doing wrong? Is it even installable on Windows 2003 Server? If so, what should I pay attention to?

Thanks in advance.

Update. The following advice worked: run the installer in Windows XP compatible mode (see inside). Thanks!
