error launching .7z with rcb 2.0.17

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Add Rom Collection (ROM folder contains .7z archives)
2. Click on a game that is contained in a .7z archive.

What is the expected output? What do you see instead?
I expect the emulator I've selected Snes9x_next to open with ROM loaded.  
I get an error: "Error launching .7z file.  Please check XBMC.log for details."

The log contains an error to the effect of: 
23:15:11 T:140132527089408  NOTICE: RCB_ERROR: You have tried to launch a .7z 
file but you are missing required libraries to extract the file. You can 
download the latest RCB version from RCBs project page. It contains all 
required libraries.
23:15:11 T:140132527089408  NOTICE: RCB_ERROR: Error: No module named py7zlib
23:15:11 T:140132527089408  NOTICE: RCB_ERROR: Error handling compressed file

What version of the product are you using? On what operating system?
i have rcb 2.0.17 with retroarch on OpenElec 4.2.0 generic 86-64 also i386

Please provide any additional information below.
i have downloaded the module py7zlib.py but i have no idea where to put it or 
even if i downloaded the right file for my system

ok after doing some more research I've found that it could have been the 
install that caused it so I deleted the zip package as well as rcb in userdata 
& addon that worked but ended up with a new error 
NOTICE: RCB_ERROR: Error: 
/storage/.xbmc/addons/script.games.rom.collection.browser/resources/platform_lib
raries/Linux64/pylzma.so: undefined symbol: Py_InitModule4

So I guess I need pylzma to be compiled with the python that openelec 4.2.0 use 
which I think is 2.6 or 2.7 I don't know & im not that good with Linux to 
compile it
