JSI Tip 10110. How can I retrieve the Fully Qualified File Name of an installed Program.exe?

Many installed programs that are NOT necessarily in your %PATH% have their FQFN at the default Value Name of a Command sub-key of the HKEY_LOCAL_MACHINESOFTWAREClassesApplicationsShell registry key, where is the program name, like WINWORD.EXE or OUTLOOK.EXE.

I have scripted WhatPath.bat to return the FQFN if it is available at HKLMSOFTWAREClassesApplicationsshell.

The syntax for using WhatPath.bat is:

[Call] WhatPath Program.exe FQFN

Where:

Program.exe is the program name, like WINWORD.EXE or OUTLOOK.EXE.FQFN        is a call directed environment variable that will contain the FQFN            (Fully Qualified File Name) of Program.exe.

WhatPath.bat contains:

@echo offif {%2}=={} @echo Syntax WhatPath Program.exe FQFN&goto :EOF setlocal ENABLEDELAYEDEXPANSIONset prog=%1set prog=%prog:"=%set pp=%prog%set OK=Ncall :quiet>nul 2>&1if /i "%pp:~0,12%" NEQ "rundll32.exe" set pp="%pp%"endlocal&set %2=%pp%goto :EOF:quietset qry=reg query "HKLMSOFTWAREClassesApplications%prog%shell" /sfor /f "Tokens=2*" %%a in ('%qry%^|find ""^|find "REG_"^|find /i "%prog%"') do ( if "!OK!"
