Actual Installer Help \ Commands
For creating flexible installations, in your Actual Installer project you can specify any custom commands to be executed on user's system.
To add a command go to the System \ Commands tab and click Add.
File - Specify a file to execute or an URL to open.
Parameters - Specify command line parameters / switches to be passed to the file when it is run.
Launch on OS - Specify 32-bit, 64-bit or Any Windows bitness under which the file should be executed.
Show - The window state at startup.
Timing - Specify when the file should be executed: Before Installation, At User Information dialog, At Folder Select dialog, After Installation, Start Uninstallation, Before Uninstallation, After Uninstallation.
Timing Before Installation executes commands when the setup program is launched.
Timing Start Uninstallation executes commands when Uninstaller is launched, but before a message asking user to uninstall.
Timing Before Uninstallation executes commands when Uninstaller is launched, and the user clicks YES when prompting to uninstall.
IMPORTANT: Do not use files from folder <InstallDir> for the Timings Before Installation, At User Information dialog, and At Folder Select dialog because they are not created yet. To be able to execute that files, they have to be located in the <SetupTempDir> folder.
Wait for process to finish - The installation waits for the given file to terminate before continuing. When using this option the setup program will store the exit code of the command in the variable <ExitCode>
Run as admin - The file will be launched with administrator privileges.
NOTE: You don't have to select this option if you already selected the option "Administrator Privileges" (on the General \ Requirements page).
Launch the 'Updater.exe' file in the silent mode (parameter /S):
Windows Command Prompt
Also, it is possible to use the Windows Command Prompt (by executing a file cmd.exe which is located in the system directory of Windows: C:\Windows\System32).
To execute a command you need to launch this cmd.exe file with specific command-line parameters which should begin with /C (executes the specified command-line and then exits). To see the result of the command it should begin with /K. More information here.
To create an empty folder you need to execute:
C:\Windows\System32\cmd.exe /C mkdir "C:\New Folder"
In Actual Installer project you need to specify it as:
Parameters: /C mkdir "C:\New Folder"
Launch on OS: Any
Timing: After Installation
Run as admin: No
IMPORTANT: In the Parameters field all file / folder paths containing spaces must be quoted.
List of useful commands:
Create an empty folder:
mkdir "C:\New Folder"
Delete a file:
del /Q "<InstallDir>\file.exe"
Delete a folder with all files and subfolders:
rmdir /S /Q "C:\Folder"
Change the folder attribute to 'Hide':
attrib +H "<InstallDir>\Folder"
Close / terminate Notepad:
taskkill /F /IM notepad.exe /T
Install MSI package:
msiexec /i "<InstallDir>\File.msi"
Check if the file exists and then rename / move it:
IF EXIST "C:\File.exe" ( MOVE /Y "C:\File.exe" "C:\NewFile.exe")
Import registry keys from a .REG file:
regedit /S "<InstallDir>\file.reg"
Launch a file on Windows 7 only:
/C IF /I <WindowsVersion>==6.1 "<InstallDir>\File.exe"
Variable <WindowsVersion> contains Windows version number:
6.1 Windows 7
6.2 Windows 8
6.3 Windows 8.1
10.0 Windows 10
== means Equal. Compares strings

Disable & enable WOW64 Redirection:
Actual Installer generates 32-bit setup files, which can be used to install both 32 & 64-bit applications. If you app is 64-bit, then you just need to select the option "64-bit only" on the page "General \ Requirements \ Operating System". In this case the setup program automatically disable WOW64 System for file and registry operations, so the setup program access the correct 64-bit paths, e.g.: "C:\Windows\System32".
If your app is 32-bit and you install it on 64-bit Windows, then when trying to access files in "C:\Windows\System32" it will be automatically redirected to "C:\Windows\SysWOW64" by WOW64 System. To access the "real C:\Windows\System32" you may use the path "<WindowsDir>\sysnative" or disable the WOW64 redirection using the Commands.
Disable WOW64: add a new command and in the File field type WOW64OFF
Enable WOW64: in the File field type WOW64ON
The Parameters field leave empty.
Caution: Always turn on the WOW64 after it was disabled and the main command is finished (set Wait to 'Yes')! Otherwise other file operations may fail.
First add a command WOW64OFF, then add a command for the operation in System32, and finally add a command WOW64ON to turn it back.
Condition for command:
If you want to launch a file (or copy, move, etc.) with condition then use the following format:

If setup language is French then launch File.exe:
Parameters: /C IF /I <Language>==French "<InstallDir>\File.exe"
If language is French then copy file "French.lng" from SetupTempDir to Installation Directory:
Parameters: /C IF /I <Language>==French (COPY /Y "<SetupTempDir>\French.lng" "<InstallDir>\French.lng")
If you want to show a message or halt the installation, use the following format:
File: IF <var1>=<var2>
to show a message:
Parameters: MSG(your message)
to terminate the installation:
