Did you disable the UAC in Vista for the install?
Do (or did) you have any other AV installed prior to Avast, and which one?

For info, images (up to a certain size) can be uploaded direct to the forum. Click "additional options" when posting to upload an image.

Do I have to disable UAC?
No, I did not have any av installed.
Did you see the images?

1) Yes.
I'm not a Vista user, so don't know that much about it, sorry, but you have to install it under the equivalent of an admin account. Error numbers including the ocx000005 are often to do with access, that's what me think of that.
2) Unusual. Not even a trial that came with the 'pooter?
3) Yes, by c&p the urls. I can show you how to link, if you like.

I had the UAC disabled, and did not work either.
What else  could I do?

Confirm that there wasn't even a trial AV with this computer?
Any other security software installed?
If no, how long have you been operating without security software? It's possible you have malware that is preventing the installation.
How much free HD space do you have?

I was using AVG before trying installing Avast. I unisntall AVG completly.
Yes i have :Spybot, CCleaner, Spyware Blaster, Windows Defender, Windows Vista Firewall,;non of this interfere with the avast installation.
I have  162gb free space.

OK. Go here http://www.avg.com/download-tools download the AVG removal tool. It should be the first tool on the page, since you are running 32bit Vista.
Run the tool, reboot, try again to install Avast.
It is (just) possible your download of Avast was corrupt. So if the above doesn't work, try downloading a new Avast install file from here: http://www.avast.com/eng/avast_4_home.html

I did every thing you said.No luck, I got the shortcut,after the installation  but once I click on it, those popups come all over again.

[Tarq57]

What do you mean "I got the shortcut, after the installation"?
If there is anything in the Vista equivalent of "add remove programs (I think it's manage programs?)" in the control panel, is Avast listed?
If so, click "change/remove" then "repair".
I f still no luck, download the Avast uninstall utility http://www.avast.com/eng/avast-uninstall-utility.html and run it, reboot, and try a fresh install.

If anyone else has any bright ideas, hopefully they'll be along shortly. I'd also be looking at possibly disabling Windows Defender during the install, but that's grasping at straws a bit.

Sorry, I did that many times over.(6)?
I've uninstall Avast and Installed it (clean install).I did unisntalled from avast utility, and from Programs and Features,(Add and Remove Programs),after that, I deleted its folders from Program Files and also from the Registry keys, mensure no even a smallest file remain.I  have installed the latest version and also an old one, all very fresh and clean installations.No luck.
What else can I do?.Say goodbye to Avast?. I love it.

OK. Sounds like an infection is preventing the install. Time to bring out the online scanners, and antirootkit apps.
This posthttp://forum.avast.com/index.php?topic=38983.msg327358#msg327358 by DavidR has some suggestions for antirootkit applications.
I suggest an online scan, also. Try some of these sites:

I did some virus scan plus spyware,etc, and my machine is free of infecccions.
Did you see in one of the pics, its a problem  with one dll file (ntdll.dll), I did  installed in the avast.ini, and it did not solved the problem.

[Tarq57]

What did you scan with?
Yes, I did see the pics. I don't have the references to make any kind of diagnosis based on what the error numbers are, especially from afar. The basic error type indicates a type of access denial. Other posts in the forum have alluded to the possibility that a particular type of malware that is current right now can cause this - a Beagle variant.
So I want to know how you know your machine is clean? (ie: what did you scan with.)

You could look at each of the ntdll.dll files on your computer to see that they are the same, I guess. It's a slight possibility one is corrupted, but i think you'd be getting other symptoms if that were the case.

Should I give up?.
If AVG, Spybot, Spyware Blaster, SuperAnti Spyware, CCleaner, Windows Defender, can't find anything, and my computer runs fast and like a charm.
Last night I gave it another try to install avast from their website, A nice clean inatallation.
Same results. Maybe there is something in my computer, that prevents Avast from install.
What else I should do?
