I am getting a “There was an error while changing the product configuration” message when attempting to install the latest version (4.8.1290) of Avast over the previous version on an XP SP3 machine.
Avast is the only anti-virus that has ever been installed on this machine. I tried shutting down all services and disabling protection as well as all running processes but still get the same error.
I manually downloaded the setup file twice in case the download had become corrupted. I have a dial-up at home, so I always download from work, save to a usb stick and transfer it. I have been doing the same procedure for years each time a new version is released without a problem.
Before I try uninstalling, then reinstalling, thought I check to see if there was something I have overlooked.
I won’t be able to help you directly with your question since I am not an expert. However, Two things you should keep in mind. If you want help try to give a more detailed explanation. Are there other security programs on your computer. What are the other specs of your machine. Have you had problems with your computer recently? etc.
Also, and people may disagree with this, but this appears to be a separate thread and should be posted as such. But I think this doesn’t really matter that much so, never mind.
I am however curious to see the resolution of your problem since I also have a system that runs Win. XP SP3. I haven’t done the avast update for that one but am thinking of doing it sometime in the future.
NOTE: My day to day OS is Vista. The computer running XP is for backup purposes only (in case the other fails)
I checked the setup.log and found this Return code entry:

I found that odd since I received a new key on Mon, 20 Oct 2008 5:40 pm which I entered that same day. Anyway I re-entered the license key and successfully updated via the program updater after borrowing a usb broadband airmodem.
