Photosmart C410b loses connection to Solution Center

Question

Dear Forum.
My Photosmart C410b loses connection to the Solution Center (“HP Photosmart Prem C410 series Disconnected!”). If remove and reinstall the HP software (latest version from the Web) it works for a while but the problem reoccurs. In the past, it has been working for longer periods. Browsed this forum for a solution but was not successful (many seem to have some form of ‘Solution Center Disconnect’ issue (!!))
I would very much appreciate advice from this forum to structurally solve this (very) nagging issue!
More details:
-       Product name: “HP Photosmart C410b”
-       Product number: “CQ521B”
-       Firmware version: “VAx2FN1121AR”
-       Windows 7 Ultimate, 64bit
-       PC connected wired to router
-       Printer connected wireless, signal quality 5 (1=low, 5=high)
-       Printer gets IP address from DHCP server (address reserved for the printer via its MAC address)
-       Printing from Windows works OK, Airprint works OK
-       Printer can be reached directly via its IP address in a browser
-       Using Microsoft Security Essentials and Windows Defender
-       Restarting PC and/or printer does not help
-       Power cycling printer does not help
-       Deactivating the “Windows Firewall” does not bring the connection back
-       Removing and reinstalling the HP software helps (for a while)
-       HP Print and Scan Doctor (HPPSDr version 4.1) detect this printer
-       HPPSDr completes ‘Fix Printing’ without problems
-       HPPSDr fails’Fix Scanning’ on the second test ‘Driver Check’ after passing the ‘Device Manager’ test. “Fails” in this case means it just hangs and the only way to close HPPSDr is to use the Task Manager to kill it.
-       I also have a G4050 scanner installed (USB) and this one passes HPPSDr ‘Fix Scanning’ without a problem
Thanks in advance,

Dear Teri,
Thanks for the suggestions. I followed your advice, please note my findings:
- I followed 'method 1' as suggested. However, I found multiple instances of the ...\temp\7zXXX\... folder containing the uninstall_L3.bat file, I randomly picked one, all these batch files seemed identical
- to run the batch file, one needs to set the default folder to point to the folder containing ccc_uininstaller.exe (which also contains uninstall_L3.bat. To that extend, I opened a CMD window and navigated to that folder and started uninstall_L3.bat from there
- uninstall_L3.bat ran without any error message, but also wanted to delete stuff related to my otherwise properly working G4050 scanjet. I accepted all. There were multiple requests for the G4050.
- I thereafter ran the freshly download installer for Windows 7 64 bit. This installar also ran without any error messages.
- The results is a connecetd C410b (but it would do this anyhow after each reinstall, the proof of the pudding is after some time: will it remain connected?)
-However...
The Solution Center now offers only the options to transfer images and to send a fax, there is no option for scanning. Also for the G4050, if I select this device in the Solution Center, there is no option at all. See screenshot:
I deliberately did not do or try anything else at this point in time, prefer to wait for your advice.
(I would guess that at a minimum I also need to run the installer for the Scanjet G4050)

Update: after a restart of the PC, things got worse: the C410b vanished from the solution center. As stated no additional attempts done to recover.
