I'm having an issue with the detection of PotPlayer in the latest version (4.1.0.4) of Patch My PC.
According to its website, the last five versions of PotPlayer, including the current one, are 200317, 200204, 191211, 1.7.20977 and 1.7.20538.
I currently have version 191211 installed.
However, Patch My PC thinks the software is up-to-date and that I have version 1.7.21146 installed, which doesn't appear to be a valid version.
I only have one (64-bit) version of PotPlayer installed, in the folder 'C:\Program Files\DAUM\PotPlayer'.
Control Panel -> Programs and Features shows that there's only one version installed: 191211.
I've also checked the registry keys HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall and HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall and again, there's only one version, 191211, under the HKLM key.
I'm running Windows 10 Pro (64-bit) Version 1909 Build 18363.
