I've tried the following script command to delete a file (outside of the MSI install procedure)
Code: Select all
Run Program del "$TARGETDIR$\\temp.bat" (WAIT)
But I found that it didn't work. This line
Code: Select all
Run Program cmd /C "del "$TARGETDIR$\\temp.bat"" (WAIT)
does work, but I was sort of wondering why the first command doesn't do what you'd think it would do..

Hmm - nothing really without digging into this further, however, I would suggest trying Run Program As -- these two functions use slightly different process creation API's.

Nico, take a look at
http://www.installaware.com/forums/view ... os+command. Does that help explain the behavior you observed?

Yeah, this seems to be the same things.
I also figured it would be because copy, del etc. are parsed by the command shell.
I needed to add the quotes so I can use paths with spaces in them
First thing I tried btw was putting the commands in a batch file, using the Write To Text File (or something) plugin. Which also worked. Only I needed to delete the temporary bacth file after that.. for which I came up with this solution
That, and I should learn to check the stickies
