As long as the menus default to English I suppose those would be ok to download. Trying to navigate through menus you can't understand to change the default language can be a challenge otherwise.
In Windows 10 when I click on the EXE file downloaded from the Ricoh Japan site (English) Windows tells me the file did not install and asks if I want to try compatibility mode. If I tell it to try compatibility the file extracts correctly - after I confirm that it worked.
I uploaded the EXE, the extracted BIN file and the BIN file ZIPped to my Google Drive. You can download them from there as these are the English versions (same files as from Ricoh Canada English).
