Problem to delete a file
Hello,

With NSIS 2.06.

In the uninstall section, i wanted to delete a specific file.

If I do the following, it works :

  
SetOutPath "$INSTDIR"
MessageBox MB_OK "Before deleting the file"
Delete "$OUTDIR\bin\flmprg.exe"

I don't want to display a message box but the following doesn't work (it doesn't delete the file:

SetOutPath "$INSTDIR"
Delete "$OUTDIR\bin\flmprg.exe"

So i'm doing the following trick but the progress bar during uninstall is "jumping"

SetOutPath "$INSTDIR"
${UnFileOrDirStatus} $R1 "$OUTDIR\bin\flmprg.exe"
${While} $R1 != "does not exist"
  Delete "$OUTDIR\bin\flmprg.exe"
  ${UnFileOrDirStatus} $R1 "$OUTDIR\bin\flmprg.exe"
${EndWhile}

Is this a bug or am i doing something wrong ?

EDIT : seems that a sleep help a little bit :

SetOutPath "$INSTDIR"
${UnFileOrDirStatus} $R1 "$OUTDIR\bin\flmprg.exe"
${While} $R1 != "does not exist"
  sleep 200
  Delete "$OUTDIR\bin\flmprg.exe"
  ${UnFileOrDirStatus} $R1 "$OUTDIR\bin\flmprg.exe"
${EndWhile}

SetOutPath "$INSTDIR"
Delete "$OUTDIR\bin\flmprg.exe"

what about

SetOutPath "$INSTDIR"
Delete "$INSTDIR\bin\flmprg.exe"

???

>> The current output directory

It may easier with

SetOutPath "$INSTDIR\bin"
Delete "$OUTDIR\flmprg.exe"

I didn't think that the OutPath had anything to do with deleting...

So do you know why 'Delete "$OUTDIR\flmprg.exe"' in the uninstall section doesn't work all the time ?

Is the file in use? Does this bring up a popup box:

ClearErrors
Delete "$OUTDIR\flmprg.exe"
IfErrors 0 +2
MessageBox MB_OK "Oops, I got an error!"

I get an error, the .exe is used to start a service but the service is stopped before trying to delete the file (i've check in the Services Windows Admin Tools).

I'll keep my "While Loop" solution.

Thx

This:
SetOutPath "$INSTDIR"
MessageBox MB_OK "Before deleting the file"
Delete "$OUTDIR\bin\flmprg.exe"
Is the same as using this:
MessageBox MB_OK "Before deleting the file"
Delete "$INSTDIR\bin\flmprg.exe"

Try this:
ClearErrors
Delete "$INSTDIR\bin\flmprg.exe"
IfErrors 0 +2
MessageBox MB_OK "ERROR!"

Still the same problem

I get the "ERROR!" message box

  ClearErrors
  Delete "$INSTDIR\bin\flmprg.exe"
  IfErrors 0 +2
  MessageBox MB_OK "ERROR!"

I don't get the "ERROR!" message box

  ClearErrors
  MessageBox MB_OK "Before deleting the file"
  Delete "$INSTDIR\bin\flmprg.exe"
  IfErrors 0 +2
  MessageBox MB_OK "ERROR!"

Try replacing the MessageBox MB_OK "Before deleting the file" with Sleep 2000

I'm guessing you aren't giving it enough time to close before deleting it (and the MessageBox is)

You are right Afrow UK, it was windows that's taking time.

With a sleep 1000 instead of the message box i escape the ERROR! message.

Thx
