Since I have been through several upgrades of CCleaner, I have not had any problems with opening any Office App. I still have a problem with Soda PDF 5, but that issue has nothing to do with CCleaner. My original report about CCleaner was resolved after I uninstalled and reinstalled CCleaner. I have Windows 10 2022H2 Pro, 64-bit.

Well, Yesterday, I received a notice that 6.05 was now available, and that I should upgrade. I was concerned that, by the time I was done installing it, my MS Office 2019 apps would be disabled. Fortunately, that did not happen. However, something new happened. I have Lulu Software's Soda PDF 5 installed on my computer. When I tried to open that software yesterday evening, it appeared to start up and then shut down immediately: the program's GUI didn't even make an appearance. I had to uninstall Soda PDF 5, use Ccleaner (the Pro version) to get rid of Soda PDF 5's Registry entries, then restart the computer, then reinstall Soda PDF 5. After that, Soda PDF 5 worked correctly. I did open a docx file in Soda PDF 5, and noticed that, momentarily, MS Word ran (embedded) to be able to load the docx file into Soda PDF 5. To me, this AGAIN speaks to flakey things happening during the upgrade of Ccleaner (its installation procedure), not during running / usage of Ccleaner. If there were another way to install Ccleaner, I would love to try it.

Then tell us, explicitly, which logs you want to examine, so we can attach them to this thread.

My version of Office is 2019 click-to-run; I don't want "Microsoft 365" on my computer. I do not use OneDrive or Google Drive. Since I don't have Windows 11 (my computer is considered non-compliant by Microsoft, because I have an older Xeon processor, and I don't have TPM 2.0), that's why I have Windows 10. In my case, I just executed the upgrade to CCleaner, then did the restore, which left 6.04 in place.

Since I did the restoration, I have run CCleaner several times for manual cleaning. I never have had a problem with running CCleaner - only when I installed it. When I clicked on every icon to execute an Office application, it was as if my request had been ignored - so far as I can tell, each app never started (as opposed to starting and then aborting). Someone else in this thread reported that after an older version of CCleaner was installed on their computer, they couldn't access Office apps, either. Naturally, I didn't think to look at the links behind the icons to see whether those links had been buggered. All I know is that, after I did the Restore, the apps were all accessible again.

Sorry to hear about your troubles, but in my case the situation was different. I upgraded CCleaner from version 6.0.3 to 6.0.4. After doing so, ALL Microsoft Office applications wouldn't even start up. I told Windows 10 (x64, Pro) to roll back to a previous Restore Point. After I did that, all of the Office applications started working again, DESPITE the fact that CCleaner's version stayed at 6.04.

Well, of all of the info that you provided, by far the most telling is that, in 2019, a user reported that they couldn't run Office apps after a Ccleaner install because the links were all lost/damaged. Sounds like my problem. My version of Windows is, as I said, 21H2. 19044-2006. My Vipre is 11.0.6.22 - 32-bit. The engine is 3.9.2671.2 - 3.0. My version of Office is 2019, Build 15601.20148. I glanced at the Ccleaner log, and, from my limited perspective, I didn't see any suspicious entries. There are other Ccleaner logs, but one of them I couldn't open (in use by another program), and the other one didn't have any logical info in it. I use Ccleaner Pro, not the free version. Even though it has features such as driver updates, I have that control set to 'notify', as opposed to 'just do it'. I have been burned in the past by driver updates that messed up my computer, so I don't allow blanket updates to occur. My computer is a Dell T3600 desktop, purchased in 2013, so it is getting older, and won't run Win11. Replacing it, with all of the reinstalls of software, fills me with dread.

The version of Windows that I have is Windows 10 21H2. I had already installed the September patches the previous week. I installed only the quality patches (cumulative update and the .Net update, as well as the update for security). Nothing else was offered to me. Even though everything appears to be working again, I am waiting for CCleaner tech experts to explain what happened, since other Win 10 users could get the same problem, potentially.

I do not use Avira. I use Vipre as my security suite.

Yesterday, September 20, my Windows Pro x64 computer was running fine. This morning, I was notified that the new version, 6.04, was available. So, I installed it. After Ccleaner was installed, I wanted to get emails - so I started up MS Outlook 2019. So far as I can tell, it never started. Then I tried to start MS Word 2019. Same thing. Then I tried MS Excel 2019. Couldn't start it, either. Then I sent 4 HOURS restoring Windows back to Monday morning September 19th. When my computer finally restarted, a popup came up saying that restoration hadn't been completely successful. BUT when I tried those MS Office 2019 apps, they all worked again. How to fix this? This is the very first time that I have had a problem with Ccleaner installation, and I have been using Ccleaner for years.

Yes - you can use the same email address registered in the forums account. For now, I have gotten around the problem by disabling the startup of LogiLDA.

Well: I uninstalled the Logitech program from the Apps List. Didn't help at all. I uninstalled the mouse, shut down the computer, and powered it up again. Didn't help. I am now trying to remove the DLL from Startup. As far as I'm concerned, your Driver Update program messed up my computer, and the suggestion that you made, while it may ultimately work, does not get to the root of the problem: the fact that I unselected that I wanted the mouse driver to be updated should have left all of the mouse driver software alone. Driver Updater has a bug.

I ran the test for the first time. I was told that there was a driver update for my LogiTech mouse. I did not want the new driver, so I unchecked it. After all of the other updates were installed, my computer restarted. After I log in, I get the message about a missing DLL. See the attached screen shot. I went back to the Driver Updater, which told me that I had a mouse driver update. I said to install it. After powering up and logging in to the computer, I get the SAME error message. What do I do about it?
