I'm trying to install Toad for oracle client, my Toad version is 12.1 for 64 bit system, i have succeeded to install oracle client 12c for 64 bit system, but i have stumbled by a problem when installing the Toad, the error is :

The content of the 'Toad for oracle 12.1 64bit.msi.lo' file is available via this link (beacause his size is big and we can not write it here):
Toad for oracle 12.1 64bit.msi.lo
Can anyone here help me please, Thanks in advance.
