As of today I have downloaded Comodo Firewall several times from different computers. When I try to install it on my 32-bit version of Windows 7 Ultimate I get to about 99% then the 1603 error message pops up.
I have used the Comodo clean up tool between installs but I still get the 1603 error message. No anti-virus is installed at this time (clean install).
I have since read that there are problems with the new version of Comodo and Avast. Since I will use Avast I just downloaded the previous version. No problems for now and I will stay away from v6 until fixed.
Thanks for the help,
PS: I thought I posted to the wrong group so I posted in the right group and used the Delete button to remove the first post. Well, after I re-posted the message the delete gave me an error message and I was stuck with 2 posts, sorry.
This could have been due to timing, I may have posted in the other topic as you went to delete it or before.
Considering it was done in error and you tried to delete it, I will remove it for you.
