App installer

[Dunnowho69]

Hello guys,
I was trying to make a simple appinstaller but no matter what i try the uninstaller always leaves behind some files telling me to remove them manually. But i want all the files to be deleted automatically even if the app was running. Would be really grateful if someone could provide me with such a script or guide me on how to do it :o

You cannot delete files when that are currently being used by a running program.

Then how about killing the processes or something like that to delete the files? I have seen some where even if the app was running it still deletes all the files somehow.

Does the deletion not work for you?

[UninstallDelete]
Name: {app}; Type: FilesAndOrDirs

Thank you both for the suggestions but none of them worked for me unfortunately. It seems the only option is to schedule a proper removal during next startup.

[UninstallDelete]
Name: {app}\*.*; Type: FilesAndOrDirs

Is the syntax correct? Dont know...
{app}\*.* !!!!
Give it a shot...
