When trying to install Aptana Studio 3.6.1 (on WinXP) I get an error: "Failed to correctly acquire installer_nodejs_windows.msi file: CRC error".
I downloaded node.js windows installer from nodejs.org and installed it, but next trial to install Aptana failed. I copied the file to "/AppData/Roaming/Appcelerator/Aptana Studio/installer_nodejs_windows.msi", but next Aptana installation trial failed with the same error message.
