I’ve been getting “Invalid Update Control CTF File” errors for quite some time whenever I try to update my local copy of AVG Free, the virus protection I use on my Windows boxes. I finally dug around and found the solution to the problem.
Some of the downloaded files are corrupt. (I actually assumed that from the error I received. Is nice to know I was correct.) You have to go into your Windows Explorer and delete the *.ctf temp files in C:\Documents and Settings\All Users\Application Data\Avg8\update\download\ Don’t delete the *.bin files as those are the ones that were compiled on previous updates. (It would be nice to see them all made into one file though.)
I hope this helps someone.
Update: I know I wrote this post for WinXP users but Doug notes in the comments below that Vista users can find AVG’s saved files in the C:\ProgramData\avg8\update\download subdirectory.
Breakfast was cool. Had eggs, bacon, and biscuits. I think I was the only non-church person there so i had to introduce myself a number of times but I didn’t mind. I walk by the church twice every day when I head over to UNCC. Didn’t get any pictures as my batteries died with the other breakfast this morning under the bridge.
I finally got a chance to look over the most read posts for January. I probably should do some sort of Top Post widget in the sidebar. (edit: Done now.)
Looks like they updated the computers here in the Atkins Library again here at UNCC. Every time they do so, we get stuck with the “Updating your computer is almost complete – Restart Now?” message with a five minute countdown. Rebooting doesn’t help as that message pops right back up 30 minutes after the reboot. Over and over again.
It’s real simple to fix although you have to go into the system settings to do so. That will give some folks the willies but it’s fairly easy.
Click on the Start button like you were going to start up a program followed by the Run icon. You’ll get a small popup that includes an “Open:” field. Type or copy in “gpedit.msc” without the quotes and click on the OK button. You’ll get a new window that sort of looks like the file manager included with Windows.
Here’s where you have to do digging but we’re looking for something that’s found in a very specific place within the system. Look at the column along the left hand side and travel these levels until you reach the final one:
Local Computer Policy
When you click on the Windows Update folder, you’ll get a long list of records in the right hand side window. Look for the one labeled “Re-prompt for restart with scheduled installations” and double click on that to pull it up for editing.
We have to change both settings within that window. You can choose any number between 5 and 1440 minutes (That’s 24 hours in case you didn’t know) and you have to click on the enable selector.
Not done yet. When you exit out of that window, it saves your settings but you still need to tell your computer to pay attention to the changes settings.
Open up the Run box again and type or copy in “gpupdate.exe /force” without the quotes and press ENTER.
