Eeek - my app has disappeared

[NewsArchive]

My app has disappeared along with all my data. I know why but need an urgent
fix. I have to say it is probably of my own making.

Following JP's advice (and I am not blaming him <g>) I created a custom
uninstall. I tested it rigorously in all scenarios and it worked fine.
Pretty simple stuff:

! Get the registry install and data paths
Set Variable %INSTALL_PATH% to FUNCTION:Get Registry Key Value("Install
Path") from "HKEY_LOCAL_MACHINE\Software\Ambrit Software\Dentists Manager"
Set Variable %INSTALL_DATA_PATH% to FUNCTION:Get Registry Key Value("Data
Folder") from "HKEY_LOCAL_MACHINE\Software\Ambrit Software\Dentists Manager"

! --- Process uninstall queue ---
Process Uninstall Queue

! Delete the remaining folders and files including registry entries
Delete Tree "%INSTALL_PATH%"
Delete Tree "%INSTALL_DATA_PATH%"
Edit Registry (Remove key and all subkeys) "HKLM\Software\Ambrit
Software\Dentists Manager"=
Edit Registry (Remove key and all subkeys) "HKCU\Software\Ambrit
Software\Dentists Manager"=

The thing is I performed a web update within my app. This closed down my
application as it should but failed at about 75%. No idea why but that's not
important. SB asked me if I wanted to rollback the changes to which I said
YES as you would.

When this has happened before (without a custom uninstall) it was not a
problem but now the custom uninstall has clearly been actioned and has done
what it should I suppose.

So how do I prevent this custom uninstall running in a scenario where there
is a rollback?

Friedrich, I know you do not support custom un installs but I did not change
the standard one created by SB other than wrapping the Process Uninstall
Queue with the lines.

Many thanks

Hi John,

Yes, it's of your own making ;-) You instruct the uninstall to remove the
database folder tree, etc. whenever the uninstall processes uninstall
actions.

See attached screenshot. Check if the uninstall is running in "smart
rollback" mode. If this is the case (%ROLLBACK_MODE% variable is set to
"1"), do not execute your custom uninstall stuff.

Or this (see attached screenshot) in your custom uninstall script:

Hello Fredrich,

You mean this as custom uninstall script ?

!
//////////////////////////////////////////////////////////////////////////////////////////////////

#pragma UNINSTALL = "1"

Set Variable %ROLLBACK_MODE% to "0"
Set Variable %UNINSTALL_COMMANDLINE% to FUNCTION:Get System
Info(Command Line)
If %UNINSTALL_COMMANDLINE% Contains "/UR" Then
Set Variable %ROLLBACK_MODE% to "1"
End

If %_SB_INSTALLERFLAG% Does Not Equal "1" on Position
"$SB_SILENTMODEFLAG$" Then
Display Message Box "#UNINST_CONFIRM#" -- "#UNINST_HEADING#"
Else
Set Variable %_SB_RETURN% to "$IDYES$"
End

If %_SB_RETURN% Equals "$IDYES$" Then
! Get registry values on PATHS
Set Variable %INSTALL_PATH% to FUNCTION:Get Registry Key
Value("Directory Installation") from
"HKEY_LOCAL_MACHINE\SOFTWARE\CGF\Data Management Center"
Set Variable %INSTALL_DATA_PATH% to FUNCTION:Get Registry Key
Value("Directory Data") from "HKEY_LOCAL_MACHINE\SOFTWARE\CGF\Data
Management Center"

! --- Process uninstall queue ---
Process Uninstall Queue

! Delete all folders and keys
Delete Tree "%INSTALL_DATA_PATH%"
Delete Tree "%INSTALL_PATH%"
Edit Registry (Remove key and all subkeys) "HKCU\SOFTWARE\CGF"=
Edit Registry (Remove key and all subkeys) "HKLM\SOFTWARE\CGF"=

If %_SB_ERRORCODE% Equals "0" And %_SB_INSTALLERFLAG% Does Not Equal
"1" on Position "1" Then
Display Message Box "#UNINST_FINISH#" -- "#UNINST_HEADING#"
End
End

Merci
(cheking to be sure I do not do a blunder)

Hi JP,

As far as I can see, you only set the %ROLLBACK_MODE% value, but you do not
really "use" it.

For example, if you don't want to execute your custom uninstall actions in
case of a smart rollback scenario:

If %ROLLBACK_MODE% Does Not Equal "1" Then
! Delete all folders and keys
! Yada yada
End

So now it looks like this :


#pragma UNINSTALL = "1"

Set Variable %ROLLBACK_MODE% to "0"
Set Variable %UNINSTALL_COMMANDLINE% to FUNCTION:Get System
Info(Command Line)
If %UNINSTALL_COMMANDLINE% Contains "/UR" Then
Set Variable %ROLLBACK_MODE% to "1"
End

If %_SB_INSTALLERFLAG% Does Not Equal "1" on Position
"$SB_SILENTMODEFLAG$" Then
Display Message Box "#UNINST_CONFIRM#" -- "#UNINST_HEADING#"
Else
Set Variable %_SB_RETURN% to "$IDYES$"
End

If %_SB_RETURN% Equals "$IDYES$" Then
! Get registry values on PATHS
Set Variable %INSTALL_PATH% to FUNCTION:Get Registry Key
Value("Directory Installation") from
"HKEY_LOCAL_MACHINE\SOFTWARE\CGF\Data Management Center RT"
Set Variable %INSTALL_DATA_PATH% to FUNCTION:Get Registry Key
Value("Directory Data") from "HKEY_LOCAL_MACHINE\SOFTWARE\CGF\Data
Management Center RT"

! --- Process uninstall queue ---
Process Uninstall Queue

! Delete all folders and keys
If %ROLLBACK_MODE% Does Not Equal "1" Then
Delete Tree "%INSTALL_DATA_PATH%"
Delete Tree "%INSTALL_PATH%"
Edit Registry (Remove key and all subkeys) "HKCU\SOFTWARE\CGF"=
Edit Registry (Remove key and all subkeys) "HKLM\SOFTWARE\CGF"=
End

If %_SB_ERRORCODE% Equals "0" And %_SB_INSTALLERFLAG% Does Not Equal
"1" on Position "1" Then
Display Message Box "#UNINST_FINISH#" -- "#UNINST_HEADING#"
End
End

Looks good This will not execute the custom uninstall actions if the
uninstall is running in "rollback" mode.

/UR is the command line switch that lets you set the uninstall into smart
rollback mode (see attached screenshot). The installer uses this switch to
rollback a "failed" install.

Merci Monsieur

So the uninstaller is run from command line from the add remove
programs ?

Reading the advanced tab in project properties I am wondering :

option : 'remove installer after successful Installation'
option : 'remove uninstaller after successsful Installation'

is there not something wrong on this second option ?? I do not
understand why one would want to remove the uninstaller after a
successful INSTALLATION ?

should it not be uninstallation ? ;o)
