self packaged crx not loading in windows. please help

[ripple emulator]

Hello group,

I have a self hosted extension which I package myself. Ever since upgrading to Chrome 25 and up I cannot seem to create the crx so that it will load on a windows machine (tried xp, win7 and win8). I'm running the following command:

chrome --pack-extension=<path to extension code>

this generates the crx which loads on mac fine, but does not on windows. I get the error "cannot unzip extension". The interesting thing is that this problem seems to have been present on the chrome store as well not too long ago.

I have tried packing the extension using both Mac and windows machines and chrome versions 25, 26, and 27.

Can anyone please help me out? I'm completely stumped :(

Thanks in advance,

Dan Silivestru.
