Uninstall Related Registry Deletion Question - InstallScript

OnEnd I run the following in my InstallScript package to make it so Add/Remove programs gets a size column:

RegDBSetDefaultRoot (HKEY_LOCAL_MACHINE);
RegDBSetKeyValueEx ("SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\"+PRODUCT_GUID, "EstimatedSize", REGDB_NUMBER, "142606336", -1 );

I noticed that when I uninstall the product the key remains. So I tried adding this:

RegDBSetDefaultRoot (HKEY_LOCAL_MACHINE);
RegDBDeleteValue("SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\"+PRODUCT_GUID,"EstimatedSize");

The code works in OnUninstall (when I pass a -uninst) to the command line, but when I add it to OnFirstMaintUIBefore or OnFirstMaintUIAfter it doesn't get executed, so it doesn't work if you just use Add/Remove programs. Anything special I can do to get this to work? Is my code just in the wrong function?

Re: Uninstall Related Registry Deletion Question - InstallScript

1st question is, why is it not automatically removed during uninstall.

Do you use somewhere in your script "Disable(LOGGING)" or just for debug purpose, try a "Enable(LOGGING)"

just before the registry operations.

Re: Uninstall Related Registry Deletion Question - InstallScript

@MarkusLatz that is a great question, one of which I don't know haha. I assumed it was because i was using code to add the key so InstallShield wasn't smart enough to know to remove it by default?

As for code in my project, the only lines of custom code are our own logging, here is my full .rul file.

// Included header files ----------------------------------------------------
#include "ifx.h"
#include "define.h"

//---------------------------------------------------------------------------

function OnSetTARGETDIR()

    // In maintenance mode the value of TARGETDIR is read from the log file.
    if( MAINTENANCE ) then
        return ISERR_SUCCESS;
    endif;

    // Set TARGETDIR to script default.
    TARGETDIR = PROGRAMFILES64 ^ "AIR\\Models";

    // Read TARGETDIR from the media.
    nResult = MediaGetData( MEDIA, MEDIA_FIELD_TARGETDIR, nIgnore, szTARGETDIR );

    // Use the TARGETDIR from the media if anything was read.
    if( nResult >= ISERR_SUCCESS && StrLengthChars( szTARGETDIR ) ) then
        TARGETDIR = szTARGETDIR;
    endif;
        
	// Customize the default TARGETDIR for multi-instance application.
	// TODO: If you want something different customize the code below.	
	if( MAINT_OPTION = MAINT_OPTION_MULTI_INSTANCE  && MULTI_INSTANCE_COUNT > 0) then

		// Start with the current multi-instance count plus one.
		nId = MULTI_INSTANCE_COUNT + 1;

		// Find a unique TARGETDIR.
		while( ExistsDir( TARGETDIR ) = EXISTS )
			
			// Convert to string.
			NumToStr( szId, nId );
			
			// Update IFX_MULTI_INSTANCE_SUFFIX
			IFX_MULTI_INSTANCE_SUFFIX = "_" + szId;
		
			// Update TARGETDIR
			TARGETDIR = TARGETDIR + IFX_MULTI_INSTANCE_SUFFIX;

			nId = nId + 1;

		endwhile;

Re: Uninstall Related Registry Deletion Question - InstallScript

Okay, I try to test this on my site in the evening. May be I find a hint why it does not work ?

Re: Uninstall Related Registry Deletion Question - InstallScript

oddly enough message boxes pop up where the delete code is, so its definitely reaching that code. and if that code is in OnUninstall it deletes the key.

Re: Uninstall Related Registry Deletion Question - InstallScript

@MarkusLatz , so i added more code around it for debugging and it seems the keys aren't found... maybe something is broke in OnMaintUIBefore? I tried the following key and its failing (a key that should exist in both Wow6432 and non.

 

// Set the root key.
		RegDBSetDefaultRoot (HKEY_LOCAL_MACHINE);
		
		// Set the name of the subkey.
		szSubKey = "SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall";
		szValue  = "EstimatedSize";
		
		if (RegDBKeyExist (szSubKey) < 0) then	
			// Delete the subkey.
			nReturn2 = RegDBDeleteValue (szSubKey, szValue);
			
			// Report the results of the deletion.
			if (nReturn2 < 0) then
				MessageBox ("RegDBDeleteValue failed.", SEVERE);
			else
				SprintfBox (INFORMATION, "Blah", "%s successfully deleted.", szValue);
			endif;
		else
			MessageBox("Key not found: "+szSubKey, WARNING);
		endif;

Re: Uninstall Related Registry Deletion Question - InstallScript

Hi @DonAIR ,

I write this post the 2nd time, because the 1st one was lost .

Okay, I played a bit with a similar InstallScript project I have and moved my function to write additional installation infos for uninstall to the "OnEnd" event.

And now my registry keys remain also.

So I took a look to the manual, and oops, the "OnEnd" event is executed "always".

So that my code works I have written:

function OnEnd()

  string svIcon;

begin

  if (!MAINTENANCE) then
    svIcon = TARGETDIR ^ "InstInfo" ^ "Lcs.ico";
    AddInstallationInfo(svIcon);
  endif;

end;

And after that it works as it should. Can you try this also. Let me know if it worked now.

regards

Markus

Re: Uninstall Related Registry Deletion Question - InstallScript

Just that it is clear:

function OnEnd()
begin

  if (!MAINTENANCE) then
    //Set the Install Size in Programs and Features (in KB)
	  RegDBSetDefaultRoot (HKEY_LOCAL_MACHINE);
	  RegDBSetKeyValueEx ("SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\"+PRODUCT_GUID, "EstimatedSize", REGDB_NUMBER, SIZE_INSTALLED, -1 );
  endif;

Re: Uninstall Related Registry Deletion Question - InstallScript

@MarkusLatz priceless, I am a dolt. So essentially all my code worked wonderfully, but I was trying to delete a key that had already been removed and then OnEnd is called at the end and adding it back. haha.

 

Thank you again!
