Installed Ccleaner on 3 Home Computers but the Versions don't Match

[RichardKAJones]

I installed Ccleaner Professional on all 3 of my home computers but the versions don't match. On one of my computers, v5.66.7716 (64-bit) with Health Check was installed. On the other two of my computers an older version, v5.44.6575 (64-bit) without Health Check was installed. I paid for a 3 computer bundle to include Health Check on all computers. How do I upgrade my 2 computers with the older version that did not receive Health Check, to the newer version with Health Check, so all 3 of my computer's Ccleaner Professional programs match?

What Windows operating system do the computers with 5.44 installed have?

Version 5.44 is a very old, and now slightly broken version of CCleaner.  If you are having trouble with the CCleaner Professional Plus bundle installer (see here https://support.piriform.com/hc/en-us/articles/360028350711-How-many-computers-can-I-install-CCleaner-Professional-Plus-on-) on the computers with 5.44 you may need to uninstall 5.44 first before installing your new version on top of it.

Alternatively, if those two machines with 5.44 on them are still showing as "CCleaner Free" you may need to register them so that they know you now have the paid version (https://support.piriform.com/hc/en-us/articles/204043844--Problems-activating-or-registering-CCleaner-Professional)

I'm running Windows 10. Dave, I uninstalled and reinstalled the Ccleaner professional upgrade and it gave me v5.44 again.
