mod_virtuemart_product missing and can not be installed

[lostmail]

I´recognised, that mod_virtuemart_products is missing and after running aio installation the folder is copied to modules/virtuemart_product but I can not see the module in Administration backend to manage it ?

Any idea what could be wrong here ?

You can go to Module Manager -> click New -> select VirtueMart Products
