When you use Control Panel / Add/Remove Programs, some 32bit programs are missing from the display?

The display is built by retrieving:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\<ProgramKey>\DisplayName

Only entries with a Value Name of DisplayName are supposed to be listed.

Unfortuneatly, any DisplayName text string that exceeds 64 characters is erroneously ignored.

You can manually inspect and fix the errant entries, or you can run undn.bat.

undn.bat uses standard commands and contains:

@echo off                              setlocal                              set fix=n                              regedit /e %temp%\undnout.reg HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall                              if exist %temp%\undnin.reg del /q %temp%\undnin.reg                               for /f "Tokens=1* Delims
