I downloaded the latest version of CIS about a week ago, but hadn’t gotten around to installing it yet. I currently have Windows 8 with Comodo Firewall and AVG. There are 2 setup files that I have for CIS, called cispremium_installer.exe (130,846,200 bytes) and cav_installer.exe (130,846,192 bytes). They both say product version: 6.0.264710.2708, file version: 6.0.2566.2708
I didn’t save the link from the original download but I believe these are the pages:
I had already installed Comodo.
I purchased a licence.
I followed the help to apply the licence to the Comodo I had already installed. I eventually discovered that under Help>About there was a button named ‘Apply License key’. Ignoring the fact that in English license is a verb and licence is a noun, I hit the button and got this alert:
Title: Comodo Internet Security premium installer
text: Failed to initisalize installer. Invalid data format.
I followed the instructions on this page looking for a .MSI in C:\program Files\Comodo, but there isn’t one.
Thank you Kail. That worked. I had to copy and paste each element of the licence before it would be accepted, even though when I typed it it showed the green tick! If it is going to include zero/oh, then it would make a lot of sense to just put it in one long string that could be copy pasted in one go. The way it is is just an irritant /whinge.
