That will at least get the issue on their radar. They may even have a fix that I haven’t thought of. Give them a list of your system specs, O/S, internet connection and security software and point them at this thread so they have an idea of what has been tried.
Hi lhwparis,
Can you please let us know as what’s the value of ‘InstallPath’ entry under following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\Software\Comodo\Firewall Pro\Configurations\InstallPath
Thanks
-umesh
\Device\HarddiskVolume2\Program Files\COMODO\Firewall
this is the reg entry could it be that my c:\ is named “HarddiskVolume2” and my external drive “HarddiskVolume1” and when i disconnect and reboot drive c:\ becomes “HarddiskVolume1”.
why is there no “normal” path like c:\Program Files\COMODO\Firewall ?
Yes it is exactly the description of the bug. We will fix this with the upcoming update.
Thanks for the feedback,
Egemen

hi is there a release date for the new version fixing this bug? in the next time i have to travel a lot with my notebook so sometimes i cant use it with the external HD and i dont want to have that problem every time:( so i think i have to uninstall comodo for a time 
any chance to get a beta or something like that fiing this bug?
lol… yea, it would be nice to have a fix.
For those of us it affects… it more like a “catastrophic failure” than a bug.
However, it says a lot about how good comodo is that I have continued to put up with this since version 3 release.
It will be fixed witht the release this week guys. This Tuesday or Thursday.
There is a batch update coming this week addressing many issues. This is one of them.
