Thanks. I understand what you're saying, but... I use the install.txt created by CCleaner Uninstall tool to track versions of programs to keep my 3 computers in sync.
The last update CCleaner is showing me for SumatraPDF is 3.3.3 from 2021-08-16. SUMO shows the correct version, 3.4.2. The Properties/Details of SumatraPDF.exe shows version 3.4.2, in Program Files--I wonder if SUMO gets it from the .exe file?
In Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\SumatraPD DisplayVersion is 3.3.3, InstallDate is 20210816.
in Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\SumatraPDF DisplayVersion is 3.4.2, InstallDate is 20220528.
I guess SumatraPDF install is screwing up. Any suggestions?
