Running CCleaner 5.44, but this problem began with earlier versions.
Something that CCleaner is removing results in Windows not recognizing that MS Office products are installed.
For instance, I run CCleaner with all the same recommended items ticked -- the same items I have had ticked since CCleaner was invented. After cleaning, if I try to open "Excel," I get a dialog that says, "Wait a moment while Excel installs." It self installs, then runs fine. As long as one MS Office "re-installs," none of the other products produce the dialog when I open them.
For example, after conducting a CCleaner cleaning, if I open MS Outlook, I get the message, "Wait a moment while Outlook installs." It installs just fine. Then, if I open MS Excel, I do not get the "re-install" message.
This scenario plays out when I right-click on the Recycle Bin and select "Run CCleaner." I am not using the registry cleaner. The problem also happens when I open CCleaner and simply run the Cleaner tool.
Just in case CCleaner was removing reg keys, I excluded the following lines after they showed up during a Registry cleaning:
HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\Folders\C:\Program Files\Microsoft Office\Office14\Groove\XML Files\Space Templates\
HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\Folders\C:\Program Files\Microsoft Office\Office14\STARTUP\
HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\Folders\C:\Program Files\Microsoft Office\Office14\XLSTART\
The above entries began to appear after version 5.42, as far as I know. They definitely showed up in version 5.43. I added the lines to be EXCLUDED from scans, but excluding them did not stop the Office products from "re-installing" after a cleaning.
What must I un-tick to prevent CCleaner from causing Office products to re-install after a simple cleaning?
Thank you!
