I can`t update either using the same methods that the other user used!
I uninstalled and downloaded the setup.exe and it crashed citing the ntldll.dll error. I am Fat32 and had no trouble until today.
No just the topic ‘can’t update to 4.7.997,’ avast English version.
I’ve had to restore my last back-up image as on reboot things hung up 100% CPU but with Outpost Pro, weird couldn’t kill the process (self-protection) I got a BSOD when I tried to restart again.
So unfortunately no further data other than the images I already posted.
Downloaded installed no problem on English Vista
We’ve got it simulated now. It’s indeed a problem with FAT32 volumes.
A new version, 4.7.1001 is going out in about 30 minutes. :-[
You are the frigging man !!! Superb effort…can`t wait ;D
Thanks Vlk…
But I can’t understand why, after all this effort, you don’t call it 4.8. Indeed, a lot of things get better since the release of 4.7, in my opinion.
Great, my HDDs are indeed formatted as fat32.
I was going to try again after having created a new back-up image so that saves a little work.
Thanks for the quick response.
4.7.1001 is now out. Hopefully it will fix the problem.
Sorry for the trouble.
Thanks
Vlk
OK downloading it now.
What was it that caused the issue with fat32 formatted drives ?
In three years this hasn’t happened on any of the numerous program updates.
Download completed sucessfully and just need to reboot to finish.
It had something to do with access rights management done by the avast installer… :-\
Thanks once again for the fast fix.
Updated perfectly…thanks again for the quick fix 
Works fine on my PC. Thanks again for the fast fix. 
One thing I have gleaned from my pc and from friends attempting the update is that Win XP FAT32 presents an issue for it. NTFS, no.
This from Vlk in reply #23 and #29
So if your friend hasn’t updated to the 4.7.1001 version they should.
updated here with no problem, thnx Vlk ;D ;D
