Hello,
I just purchased hika business and tried installing it on my fresh joomla instillation, only thing i installed before hika was admin exile plugin. first i tried installing tar.gz package but it gave me error (i didn't copy message) after that i tried installing .zip package but it resulted in white screen. I hit back button and checked if there is hika in components menu-it isn't, it cant be found in extension manager. Then i went to my joomla instillation folder and in components i found hika folder with files inside it, there is also in administrator components hika folder.
What should I do now?

EDIT:
I removed database tables and deleted hika files, checked if php error reporting is on and max upload size, it was on and my max upload is more than enough.
I tried installing .zip package again. white screen appeared again. no error message no nothing, but then i hit refresh page, and istallation ''started '' . now i i got post installation screen and was able to get to the dashboard. Still i dont have link to hika shop in components menu, but in extension manager i see hika and its plugins.

EDIT2:
I managed to fix it running this from php my admin
UPDATE `e0n_menu`
SET `published` = '1',
`component_id` = ( SELECT extension_id
FROM `e0n_extensions`
WHERE element = 'com_hikashop' )
WHERE `title` LIKE '%hikashop%';
