i installed a codeblocks IDE in my flash drive while i was using windows 7. After downgrading to windows XP, the IDE won't open and an error message pops up "codeblocks.dll is not a windows dll." Pease assist in help me solving this. Thank you.

You need to reinstall CodeBlocks for XP. You can't run Win7 software on an XP system.

thanks it worked it seems codeblocks in windows 7 is not compartible with XP
