When I click “Check for Updates”, Comodo opens another window then the process just freezes. I’m unable to ■■■■ it away from the task manager and have to log out and log back in again to get it to give up.
However, that does not really excuse or explain why CFPs Update isn’t working (it should). A possible thing is that CFP uses MSIE connections tab to get its Net access (even if you don’t use MSIE). So, it might be worth checking that. Failing that, what OS do you have?
The forums and main site tell you everything you need to know about updates. There is only an update when a new version comes out but thats only about every 2-3 months or so.
Also, I said something completely different: Check MSIE (Microsoft Internet Explorer) or Internet Options (Control Panel) “Connections” tab, CFP’s Update processes uses these details to obtain its internet connection.
Ah… now a Corporate LAN might be a (or even “the”) problem. You may not be running a proxy, but Corporations often do (quite often transparent ones). Proxies aside, it’s hard to say what the LAN might be doing with (or not, as the case may be) CFPs update request. You’ll need to contact your System Administrator & ask them (they’ll have better diagnostic tools anyway).
As a test (of sorts) from your side, you could use CFP to submit an small & inconsequential file to Comodo for analysis. This process uses the same connection method, but it is very different from CFPs Update… it connects to secure servers & has a much longer negotiating dialog.
But, to be clear… as far as I am aware there is no specific problem with CFPs Update process.
