Problem compiling script with uninstall section.

Hi,

I have been battling with this script for the past 2 hours and am getting nowhere fast. I have tried the documentation, checked the sample files, checked the archives and I still cannot see what I am doing wrong.

When I compile this script I get the following error.
Processed 1 file, writing output:
Adding plug-ins initializing function... Done!
Error: resolving pre-page function "un.mui.ConfirmPre" in uninstall pages
Note: uninstall functions must begin with "un.", and install functions must not
Error - aborting creation process

Could someone please look at it and tell me what I have done wrong.

I know the script is huge, please help me with the uninstall issue.
😔

Do the example scripts with uninstall functions compile on you system or is this related to the script?

It appears to be related to my scrip as the samples do work.
BTW. It is Version 2.0B4 of the NSIS software

Yes I did get the same error when I tried to compile your script, I will try to figure something out although I can't promise anything, not tonight anyway.

PS. You were not joking when you said it was a huge script😁

Thats what happens when one's installers do not know how to RTFM 😉 Read The Fine Manual.

And we poor developers have to spoon feed them.🧟

I do agree. I once had the same problem with the uninstaller, after a while I descided to leave it out since in that program it was not essencial. However now is the time to revisit and hopefully solve this problem.

I have simplified the script and still get the same error. 😔

The simplified script does not follow the rules given in the current MUI ReadMe.

The latest MUI no longer uses Page "defines" such as

!define MUI_WELCOMEPAGE
!define MUI_DIRECTORYPAGE
etc

All you need now are the "!insertmacro" commands such as

!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_DIRECTORY
etc

If you move the

!insertmacro MUI_LANGUAGE "English"

line further down the script, say after all of the "!insertmacro MUI_PAGE..." lines, the simplified script compiles without the error you complained about in your first post.

If you read the MUI ReadMe you will find that it gives step-by-step instructions for creating scripts. Step 1 is the !include "MUI.nsh" command, Step 3 covers the new PAGE !insertmacro commands but it is not until Step 6 that the MUI_LANGUAGE commands are discussed.
