Firstly, you need to determine what type of Foxit PDF Editor installation package you have installed(.exe or .msi). Please navigate to Foxit PDF Editor's main installation folder, somewhere like：C:\Program Files (x86)\Foxit Software\Foxit PDF Editor
Right click on the "uninstall" file in the installation folder and select Properties option in the pop-up context menu to open the "Uninstall Properties" dialog box, click on Shortcut tab, then please find the content in the target field.
If the target content is something like the following:

It means that the one you have installed is .exe installer package of Foxit PDF Editor.
If the target content is something like the followings:
C:\Windows\System32\msiexec.exe /x {3EACD346-8A39-11EA-B9CD-54BF64A63C26}
It means that the one you have installed is .msi installer package of Foxit PDF Editor.
