UAC plug-in EM: install function "ExecAppFile" not referenced
Hi everyone,
When I try using the UAC plug-in (http://nsis.sourceforge.net/UAC_plug-in) inside a MUI skinned installer, I get following EM:
install function "ExecAppFile" not referenced - zeroing code (1533-1542) out.
I put the dll's and nsh files under the correct locations.
I stated "RequestExecutionLevel user" at the top of my nsi.
I included UAC.nsh.
Anyone has ideas on why this can happen?
It's not an error, it's a compiler warning. Apparently there's a function called ExecAppFile that is never called. This function doesn't exist in UAC.nsh, so I doubt it is related to the UAC plugin. The problem is probably in your own code.
If you read the documentation on the UAC plug-in wikipage, then there it says to use this to run an application after the installer has finished:
!define MUI_FINISHPAGE_RUN
!define MUI_FINISHPAGE_RUN_FUNCTION ExecAppFile
Function ExecAppFile
UAC::Exec '' '"$INSTDIR\${APPFILE}"' '' ''
FunctionEnd
That is why I use "ExecAppFile". It is indeed no function of UAC, but of UMUI.
And you're also correct that it isn't a EM but a warning. But it also says that it is zeroing out the code, which results in an installer which doesn't start up anything after it is finished.
this has nothing to do with the uac plugin. Maybe MUI_FINISHPAGE_RUN_FUNCTION is not the correct define for UMUI
Yes, sorry I mentioned it as UAC EM, it indeed is not. I just wanted to add UAC in the title of this topic.
But MUI_FINISHPAGE_RUN_FUNCTION is defined correctly for UMUI. That is, I can find it back in the UMUI.nsh file. And there it looks exact the same as in how it is defined inside MUI.nsh.
Ok guys,
I stopped using the MUI_FINISHPAGE_RUN_FUNCTION and used the function UMUI_CUSTOMFUNCTION_GUIEND instead. This worked. Thanks.
But now I have another question, I assume that this is an UAC issue, or more likely me using the syntax incorrectly. When I try to install a service trough UAC::Exec, nothing happens on Vista, whilest the service gets installed correctly on XP.
This is what I try to use:
UAC::Exec "" "$INSTDIR\Uploadservice.exe -install" "" ""
UAC::Exec "" "$INSTDIR\Uploadservice.exe" "-install" ""
Sorry to say, but that gives exact the same result. Works in XP, but does nothing in Vista.
I do see that in Vista (and XP as well) during the install a cmd-screen pops up titled "C:\Program Files\uploadservice\Uploadservice.exe" and immediately shuts down again. Is there a way that I can prevent this cmd-screen from shutting down, so I can actually see what it tries to do and maybe the error it is giving?
Thanks for the help.
well, first off, are you sure this service can be installed as non admin?
as far as stopping goes, try
UAC::Exec "" "cmd.exe" '/k "$INSTDIR\Uploadservice.exe" -install' ""
No, that just opened up an empty command prompt with no title.
But no problem, I found out that I called the UAC::Exec at a wrong location inside my code, that is why it didn't ran correctly.
So all my issues are gone. My installer works now!
Thanks for all the help Anders.
You made a great plug-in, thanks for that as well!
