instrucion at referenced memory could not be read

After updating my comodo firewall form v2 to v3 I’m getting several cryptic error messages. They all have this common structure
xxxxx.exe Application Error
The instruction at “xxxxxxxx” referenced memory at “xxxxxxx”. The memory could not be “read”. Click OK to terminate the program.

The following (and maybe more as time goes by) applications have/had this error
wmiprvse.exe
wuauclt.exe
regsvr32.exe
logonui.exe
svchost.exe

Even if I use the help file in comod firewall I get a error message wrt hh.exe.

Anybody have any idea what’s going on?

Cheers

Anybody have any idea what could be up?

Have you done clean install of v3 or upgraded from v2 through GUI?

Try to uninstall Comodo and remove all traces left behind (see here). Then re-install firewall.
