Install CIS 6 on top of CIS 5, or uninstall CIS 5 first ?

should i uninstall CIS 5 first and then install CIS 6, or can i install CIS 6 on top of CIS 5?

thanks :slight_smile:

The safest, and most reliable, approach, is to reinstall by following the advice I give in this topic. However, if you follow this approach you cannot import your old configuration.

If you have a lot of rules already created, and do not want to re-create them, you should instead use the upgrade installer provided on this page.

will check it out, thanks :slight_smile:

after running upgrade, got the following:

still CIS version 5.12.256249.2599

virus signature file: 0

firewall not working warning

I’m very sorry to hear that. It sounds like something went wrong with the upgrade installer.

If you like this can almost certainly be solved by updating via the methods I suggest in this topic.

Let me know if you have any questions, or encounter more problems.


complete disaster

cannot unistall existing 5.12, default unistaller doesn’t even see it

cannot install old version

revo installer does not recognize any version of CIS

CIS is not in revo window

what should i do?

i’m afraid to install any other type of antivirus/firewall as well

complete disaster

how can i remove CIS completely if unstaller does not see it?

is there a way to hunt for all CIS components and files?

please help, paralyzed here

ran diagostics in CIS 5.12, it found problems but it couldn’t fix them, generated a report

cannot install, uninstall, upgrade, anything, nothing is recognized

completely terrible, firewall corrupted, i really can’t do anything

tried to upgrade, install, uninstall, everything in safe mode too but still didn’t recognize anything

would this work?

or this;new;boardseen#new

scanreg, please follow the advice I give in my topic. I link to relevant uninstallers and explain the most effective way to use them.

Please let me know if you have any questions.


i had to go into safe mode and use the first uninstaller mentioned above:

and then i could install CIS 6

That’s great to hear. ;D

Let me know if you have any questions, or run into more problems.

hopefully this helps someone else too

thanks again
