FAQ: What's this _iu14D2N.tmp file in my TEMP directory?

A temporary file with a name like "_iu14D2N.tmp" is created when you uninstall a program that used Inno Setup as its installer. The reason the file remains in the directory after the uninstall process has completed is that Windows does not allow running executables to delete themselves. So what it does is schedule the file to be deleted automatically the next time your computer is restarted. If you don't want to wait until then, it is perfectly safe to delete the file manually, provided no uninstallers are currently running.

(Note that this behavior is not unique to Inno Setup. Wise uninstallers, for example, leave behind a file named GLB1A2B.EXE, and NSIS uninstallers leave behind a file named A~NSISu_.exe.)
