Ran CCleaner; Now getting DAO.msi error
I ran CCleaner on a system, and now it's saying it can't load the DAO app because it's missing DAO.msi.

I did a search and it seems to be an ATI issue.

I found three possible solutions:

------------------------

Option 1

1. Look for DAO.exe (you may have to change the setting in Windows Explorer so you can view hidden and system files)
2. Do a search for "DAO" on your C drive
3. It might be in a folder like C:ATI\SUPPORT\mmc-9-1-0-0-dao-mdac
4. Go to START>CONTROL PANEL>ADD/REMOVE PROGRAMS>Uninstall DAO
5. Then go back to the folder where you found DAO.exe and run it

OR


Option 2

1. Download and install MDAC 2.8
http://www.microsoft.com/downloads/...&displaylang=en

OR


Option 3

Go to Command Prompt and unregister DAO by typing (including the quotes):
regsvr32 /u "c:\program files\common files\microsoft shared\dao\dao360.dll"
Type OK

then...

Register DAO again by going to the Command Prompt and typing (including the quotes):
regsvr32 "c:\program files\common files\microsoft shared\dao\dao360.dll"
Type OK

It might ask you to do it again, but people have said that it is not necessary

-----------------------------------------

Which solution would you suggest?

How can this be avoided when running CCleaner again, and the DAO.msi file is in the temp folder?

Have you tried undoing all changes made by Ccleaner?
It has a backup, if you clicked Yes to backup changes.

Well, I'd rather not do that, as CCleaner was able to free up 16GB of space. I would still like to have the ability to use CCleaner in the future.

Plus, when I ran it, there was no option to backup the changes, nor do I see where you can initiate the restoration of the backup.

Hi it only backs up any changes made in the Registry cleaner.
Not the Temp file cleaner.
Did you clean the Registry?

I didn't do anything with the registry. I just used the Cleaner.

Btw, how accurate is the registry cleaner? Do you trust it? Had any problems with it?

I just did a scan on another system and it found many problems in the registry. Here are the types of problems it found:

Missing Shared DLL
Unused File Extension
Invalid Default Icon
ActiveX/COM Issue
Open with Application Issue
Applications Paths Issue
Help File Issue
Installer Reference Issue
Uninstaller Reference Issue
Obsolete Software Key
Missing Startup Software
Old Start Menu Key
Missing MUI Reference

But the DAO issue is my primary concern.

Wouldn't use any Registry cleaner.
They cause more problems than they claim to solve..many posts on this forum alone keep on proving that to be the case.

As for your DAO problem you may need to choose 1.2 or 3.

Thanks. I've never used a registry cleaner before, as I don't trust them. Thanks for the confirmation.

With regard to my DAO issue, you said I may need to choose 1.2 or 3. Did you mean I can choose 1, 2, or 3? In other words, any of the options that I found will work?

Btw, here is the link for Option 2:

All good questions.
I do not know which of those would work as I've never had the problem.
Id probably try No 2 first but I have yet to check the link.
Then maybe No 3.
