If Paperport 14.5 will not start in Windows 10:
In the registry there is an option that causes the crash:
HKEY_CURRENT_USER\Software\ScanSoft\PaperPort\PaperPort User Preferences
look for BrowserSelected
my registry had “Mozilla Firefox”
I changed it “none”
PAPERPORT 14.5 STARTED WITH NO PROBLEMS
NOTE: if it contains “Mozilla Firefox” it will not start.
