I am new to Blender. I downloaded blender-2.49b-OSX-10.5-py2.5-intel. It’s on my desktop but won’t open. Can anybody help me with this. Thank you.
Is OSX your operating system?
If you are on Windows or Linux, that installer won’t work. The ‘OSX’ in the filename indicates that the file you’ve got is for a Macintosh. Head back to Blender.org to get the correct installer for your OS.
