Error: "An unsupported operation was attempted" [Resolved]

When i try to install CIS x64 and press “Next” button on a first screen, installer says “An unsupported operation was attempted”. ??? I try to install all versions of CIS x64 since 3.5 and i get this error always. Versions prior to 3.5 installs without errors. I try to reinstall clean OS with latest hardware drivers and without any software and redownload CIS x64, but i get same result. :’( I love Comodo and i want to use it, but i can’t since 3.5 version. My PC specs: Core2Duo/4Gb RAM/Vista x64 SP1. Error screenshot in attached file.

Thanks in advance and sorry for my English. 88)

Today CIS 3.9 BETA installed without this error. Many thanks to dev’s :slight_smile:

I’ll mark this as resolved and lock it. If you wish it re-opened, please pm any Mod or Admin.
