CCleaner Uninstall Log

Hi.

Is there any way to check in the Windows un-install logs if Ccleaner was removed from my computer?

I installed it last week and it has mysteriosly disappeared. Since i am not the only one using this computer, is there any way to confirm via logs if the program was uninstalled?

Thanks.

Well.. the install directory (by default) is \Program Files\CCleaner - so you could check there for the files, but I can't answer about the logs, sorry!

If the program is uninstalled that folder is removed. So i can't confirm.

Does anyone else know if there are any uninstall logs for this programs?

It looks like i might have to contact tech support.

There may be un-install entries in the Windows System Event Logs under the Application Tab.

There is no way that any log would show that some-one has deleted the program folder.

For CC to logg its own un-instal would be unnatural - its purpose to purge junk, not create junk.

If there are other users who might uninstall CC then I think you have more important things to worry about.

I did check under the app tab, there is nothing there.

It's not unnatural for a program to leave logs after it's removed. It's actually bad programming from CCleaner.

If they used MSI for their installation/removal then there would be an event log in the Applications Tab in Windows.

But other programs which don't use msi, still leave a uninstall log when the program is removed.

It's actually bad programming from CCleaner.

It is good programming for ANY application if it is uninstalled cleanly without trace.

For any application such as CCleaner IT IS AGAINST THEIR NATURE TO DELIBERATELY LEAVE JUNK,

which is why I said it would be unnatural.

I have been designing software systems for 30 years,

and have never encountered a requirement to leave dirty footprints on the system upon removal.

The only valid reason I can think of for uninstall logs is to trace what went wrong if uninstallation is defective,

which Microsoft applications and MSI installers are prone to do.

Since i couldn't get any help from the tech support or this forum, i ran the following things on my own

1. Download regshot.

2. Take a snapshot of the registry.

3. Uninstall ccleaner

4. Take another registry snapshot.

5. Compare.

I found the following registry key:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Piriform\CCleaner]
“UpdateCheck”=“1”
“Language”=“1033”
“UpdateKey”=“01/18/2011 10:46:56 AM”
“MSG_CONFIRMCLEAN”=“False”
“WINDOW_MAX”=“1”
“WINDOW_LEFT”=“0”
“WINDOW_TOP”=“0”
“WINDOW_WIDTH”=“0”
“WINDOW_HEIGHT”=“0”

The "UpdateKey" tells me the last time CCleaner ran, so it's close enough.

Updated our wiki so other technicians can refer to non-standard un-installation practices by this program.
