~workable w/o these files, but...
no help-file (codeblocks.chm) etc
setup exe CRC correct?
so, packed with errors?
As I see in 7Zip it's Nsis arch with deflate (ZIP) method.
I don't like setup, so extract it...
7Z log (0 size file after):share\CodeBlocks\start_here.zip
share\CodeBlocks\templates\wizard\glut\wizard.png
share\CodeBlocks\templates\wizard\opencv\files\lena.jpg
and share\CodeBlocks\docs\codeblocks.chm 85 666 Bytes only (must be 7 501 204, as I see)
may be it have more broken files inside?
