I got a one year license for AIS.
I uninstalled avast! 5 Free and ran the avast! 5 uninstall tool in safe mode.
After installing AIS it wouldn’t run and I had no internet, I clicked on “fix”, but nothing happened.
Uninstalled AIS and now I have internet. Ran the uninstall tool.
Installed avast! 5 Free, now I can’t register it, filled out the form in the ui, but it failed.
Installed MSE 2, runs fine, but I want to use AIS. 
Probably if I install AIS in safe mode with networking it will work.
Maybe tomorrow.
This happened to me too when I was using AIS 5.0 on XP but I have no idea how I made it work.
Did you remember to remove zone alarm or some kind of program that could have caused conflicts?
I do not think Avast! can be installed in safe mode.
LOL, spoken to this forums resident ZA fan. ;D
Yes, I removed ZA first before trying to install AIS, as it has a firewall it would conflict with ZA. 
What?..
When 5.0 beta first appeared many of us with XP had to install it in safe mode, it was the only way.
I just installed AIS in safe mode with networking, working great AFAIK. 
Gargamel360,
Avast! Forums’ resident ZA fan is no longer using ZA, at least for a year. ;D ;D ;D
Why did you do that? Didn’t it work on normal mode?
Tech,
Did you read all posts in this thread?
In the original beta testing of avast! 5 many (includes me) had to install avast! 5 in safe mode w/networking.
Today I also had to do it. I wouldn’t of used safe mode if normal installation worked.
Tech,
I think it was doktornotor that came up with the idea to install avast! 5 in safe mode w/networking.
It sure helped many people.
Maybe if Vlk would look into what is going on with a normal mode installation of AIS compared to a safe mode w/networking installation
he could fix the problem?
They should. avast should be installable in normal mode for sure.
No :-[
I can’t read all the thread again each time I open it…
Why didn’t it work? Can you post the setup log?
Where do I find the setup log?
Please, upload (attach) the avast log: C:\Program Files\Alwil Software\Avast5\Setup\setup.log
(or the shorter C:\Users\All Users\Alwil Software\Avast5\log\Setup.log).
If the file is too big for the forum, post the last 400-500 lines of it.
Interesting, I’m still finding my way round my new win7 netbook and I don’t have a users\all users folder C:\Users\All Users\Alwil Software\Avast5\log\Setup.log. I only have c:\users\MyUserName\ and no Alwil Software sub-folder.
Tech,
I attached set up log to this post.
I don’t think I gave what you want, it kept saying too big.
You can copy and paste the last 400-500 lines of the file into a new notepad file and save that as rdmaloyjr_setup.txt and attach that to the next post and Tech should be able to view that.
