I'm using Inno Setup 5.5.9. My installer includes the settings:
[Setup]
RestartApplications=no
CloseApplications=force
When I run the installer it identifies an application as still running and correctly shows the "The following applications are using files..." page. I choose to "Automatically close...", but nothing happens - the application remains running. I see these in my log file:
RestartManager found an application using one of our files: {redacted}
Can use RestartManager to avoid reboot? Yes (0)
CurStepChanged(1) called
Must the application register with the restart manager to auto close, even though I have specified 'no' for RestartApplications?

I am building an installer in Inno Setup v6.2.1 with prerequisites, which include .NET, runtimes, and KB fixes (Windows 7 SP1). The goal is to do potentially several reboots depending on if the machine is missing KBs or .NET etc.
I am able to achieve what I want so far using PrepareToInstall and can change the text by returning the appropriate string. No problems... however I can't find a way of changing the.
Setup must restart your computer. After restarting your computer, run Setup again to complete the installation of xxxxx
Because I am creating a runonce entry, the installer will automatically run after reboot (which it does). The text "run Setup again" is not relevant in my situation and I want to change the text to say that the installer will continue once you restart.
I have tried to find where to change this text but with no success. I assume that PreparingMemo might be the candidate but no luck or not sure how to use it. Any help would be appreciated.
See Handling and customizing errors and messages in Inno Setup.
This particular message is defined by the PrepareToInstallNeedsRestart message.
You can change it in the [Messages] section:
[Messages]
PrepareToInstallNeedsRestart=Setup must restart your computer. After restarting your computer, the Setup will continue to complete the installation of [name].%n%nWould you like to restart now?
If you need to change the message text dynamically, assign WizardForm.PreparingLabel.Caption. E.g. from CurPageChanged(wpPreparing) event.
In Inno Setup, one can use CloseApplication to enable the Windows restart manager, and check for running instances. This, however, does not apply to the uninstallation. The setup removes all files that are not in use, and shows a message along the lines of "not all files could be removed, please remove them manually".
The only way to check for running instances that seems to work during uninstall runs, is to use AppMutex.
Is there a way to enable the restart manager during the uninstallation as well?
No, you cannot use restart manager in uninstaller. But you can code it yourself:
How do you close then restart explorer.exe in Inno Setup uninstall using the Restart Manager?
Simpler, but less elegant solution is killing the application in InitializeUninstall.
For that see my answer to Uninstall fails because program is running. How do I make Inno Setup check for running process prior to attempting delete?
I have created an installer using Inno Setup. The installer uses a packaged-in DLL to check availability of a specific device on the target machine. If the device is found, the installation is allowed to finish, otherwise the installation is rolled-back (rollback is done using below lines in script):
if <DeviceNotFound> then
begin
CancelWithoutPrompt := true;
WizardForm.Close;
end;
I have checked that the above check and rollback logic works fine if the setup is run with /silent cmd line param. However, when I use /silent param, the setup displays the Installation progress wizard form.
Also, I found that if I run the above setup in /verysilent mode, then the "DeviceNotFound" check logic works fine but the rollback logic doesn't work and it seems as if rollback logic doesn't get executed at all. Instead of performing rollback, the installer successfully installs.
Now, I have a requirement to run the setup silently so that no window is displayed but it must install or rollback based on device check. Therefore, I have the below queries:
Can I rollback the installer when it is running in /verysilent mode? If so, please advise how it may be achieved. I can detect verysilent install mode as shown in question:
How to detect whether the setup runs in very silent mode?
Alternatively, can I Hide/Minimize the Installation progress window when it is running in /silent mode? If so, please advise how it may be achieved.
Please help me with my above queries.
Sorry to be so descriptive but I tried to explain my problem and queries!
EDIT
I am not doing the above mentioned check in InitializeSetup(). I am doing the check from a function invoked by AfterInstall directive from [Files] section. I have a limitation that I cannot do it from InitializeSetup() as the packaged-in DLL is not extracted till [Files] section completes. I also need to run the installer in Windows PE (Preinstallation Environment), hence I cannot use ExtractTemporaryFile() function to forcefully extract the DLL because the {tmp} path is not valid in that environment. That leaves me with only one option is to check after [Files] section is done. Please advise!
Your constraint on not using ExtractTemporaryFile does not make sense.
The Inno Setup installer always creates a temporary folder for the installation.
2015-07-31 09:02:07.458 Created temporary directory: C:\Users\martin\AppData\Local\Temp\is-1CN29.tmp
If it is not possible to create the folder, the installation fails.
The Inno Setup tries to create the temporary folder in these locations:
%TMP%
%TEMP%
%USERPROFILE%
Windows installation folder (C:\Windows)
At least the last path has to exist even in the "Windows PE".
So I do not think, there's anything preventing you from using the ExtractTemporaryFile function.
I'm building an installer using Inno Setup where I need to convert some existing files if the application is already installed.
To do so I need to stop the applications service which works automatically for the install process. Is there a way to hook a page between the application shutdown and start routine? Or to postpone the application restart to a later time?
EDIT:
I also tried CheckForMutexes('MyAppMutex') to manually prompt the user to close the application, but the function always returns false.
EDIT2:
My current workarround uses the isProcessRunning script by jakoch to prompt the user to manually close the application. I would prefer a more automatic solution though.
I am using Inno Setup for the installer for my windows application. If a user has the application when the installer is run (eg. for an update), the installer will stop when it is unable to replace a file in use, and it allows the user to select whether to Abort, Ignore, or Retry.
I would like it to only allow Abort or Retry and remove the option to Ignore. Does anyone know how this can be done?
Or if this can't be done, how can I make the installer abort if the application is running?
The easy way to detect whether the application is running requires co-operation from the application, so it's best to work this out before you ship your first version. Use Inno Setup's AppMutex setting. There is an example in the Inno Setup knowledge base for setting up a mutex visible in multiple sessions. There is more about AppMutex in Inno Setup's help file.
