How to display a text message during an installation

It is possible to display a text message during an installation (that is created with Visual Installer). You can do it via Visual Installer’s script language. There are two commands available for this purpose:

MESSAGE : Displays a text message on the progress bar window.
MSGBOX : Shows a message box with a title, text and an OK button.

If you use the MESSAGE command, the text will be shown until another text need to be displayed or the progress bar is closed. If you use the MSGBOX command, the installation will pause until the end-user click the OK button in the message box.

MESSAGE
Below is an example of how to use the MESSAGE command:

MESSAGE My MSI installation is running
MSIEXEC %DESTDIR\MySetup.msi, /qn, WAIT

MSGBOX
Below is an example of how to use the MSGBOX command:

IF NOT OFFICEINSTALLED
MSGBOX Information, There is no MS Office installed in this computer! , 2
EXIT
END IF

MSGBOX The picture to the right shows how the message box created in the scripting code example above will look like when shown during an installation. When the end-user clicks on the OK button, the installation continues to the next script line, where the EXIT command halts the installation.

More information
More information about the commands described above is available in Visual Installer´s Help Documentation and User´s Guide. General information about Visual Installer’s script language can be found on this web page.

FAQ about destination folders for EXE, DLL & OCX files in Visual Installer

FAQ There are some common questions about destination folders for binary files (EXE, DLL, OCX files etc.) in Visual Installer that we sometimes get asked from our customers. You will find the questions & answers below, and if you are new to Visual Installer we recommend you to read them:

Questions and answers:

#1
Q: Should I use the C:\Program Files folder or the C:\Program Files (x86) folder as a destination for my application file?

A: It depends of the bitness of your application. 32 bit applications should be installed to the Program Files (x86) folder and 64 bit applications to the Program Files folder.

However, Visual Installer will choose correct folder automatically for you, if you specify your application’s bitness in the 32/64 bit tab in the Setup options dialog box in Visual Installer.

You can open this dialog box by choosing the Setup options menu item in the Special menu.

#2
Q: How do I do in Visual Installer to install a file to the program files folder?

A: Installing a file to the program files folder (the Program Files or the Program Files (x86) folder) is easy done in Visual Installer, but you need to specify the settings for this in two steps:

Step one:
1. Open the File list tab in Visual Installer’s editor.
2. Click on the […] button to the right of the Main folder text box in the tab (it is located in the upper right part of the editor window).
3. Select the %PROGRAMFILES option in the dialog box that is shown (see the picture below).

The Main Folder Variable Suggestions dialog box

4. Click the Select button.
5. Add (enter) a sub folder name after the %PROGRAMFILES variable in the Main folder text box. Below is an example:

Main folder

You have now specified the main destination folder for your installation. In the next step we will specify the destination folder for the specific file that you want to install.

Step two:
1. Choose the List – Add – Add files menu item in Visual Installer’s editor.
2. Select your file in the Add files dialog box.
3. Confirm that the text after the Folder text box is %DESTDIR in the following dialog box:

The Destination folder dialog box (1)

4. Click the OK button.

Now this file will be installed to the Program Files or the Program Files (x86) folder during the installation. If your application is a 32 bit application, the Program Files (x86) folder will be used as a destination. You can read more in this blog post and in this tip.

#3
Q: How do I install a file to the system folder?

A: If you have for example a DLL or OCX file that need to be installed to Windows’ system folder it can be done in Visual Installer. Follow the instructions below to do it:

1. Open the File list tab in Visual Installer’s editor.
2. Choose the List – Add – Add files menu item in Visual Installer’s editor.
3. Select your file in the Add files dialog box.
4. Select the System directory option in the following dialog box:

The Destination folder dialog box (2)

5. Click the OK button.

Now this file will be installed to Window’s system folder during the installation. The exact folder that is used depends of your installation project’s bitness (see question 1 above).

#4
Q: In some dialog boxes and other places in Visual Installer’s editor I see words like %PROGRAMFILES, %DESTDIR and %SYSDIR etc. What are they?

A: %PROGRAMFILES, %DESTDIR and %SYSDIR etc. are called variables. The name of the variable will be replaced with an actual text during the installation.

Variables are used when the actual text is not known, until the installation starts. Variables are usually used as a place holder for folder paths. For example the %PROGRAMFILES variable is a place holder for the program files folder in the system. When the installation starts, %PROGRAMFILES is replaced with the actual folder path. For example with C:\Program Files.

You can read more about variables in this blog post.

#5
Q: I have an international application. The name of the program files folder is different in different countries / languages. Can Visual Installer handle this?

A: Yes. Visual Installer will find the correct path to the program files folder regardless of country / language or version of Windows. You can read more in this blog post.

More information
If you want more information about the settings in the dialog boxes above, you can press the F1 button on your keyboard when the dialog box is open. We recommend you also to take a look on Visual Installer’s tips and tricks pages:

How to install an ActiveX component with Visual Installer

ActiveX Logotype

Visual Installer supports installation of VB6 applications, and most VB6 applications use ActiveX components. An ActiveX component is an easy way to give applications access to powerful functions in a library or to put well designed visual objects on the application interface.

Visual Installer can install ActiveX components. If you import a VB6 project to Visual Installer (via File – Import Visual Studio project – Visual Basic 6.0 project) all ActiveX components in the Visual Basic project will be added automatically to Visual Installer’s file list. But you can also add additional ActiveX components manually, in this way:

1. Choose the List – Add – Add files menu item in Visual Installer’s menu.

2. Browse to the ActiveX component you want to add.

3. Select the ActiveX file and click on Open.

4. The following dialog box is now shown:

The Destination Directory dialog box

5. Choose a destination folder for the ActiveX.
Normally is System directory used as destination folder for ActiveX files in VB6 projects. If you don’t find other information about the destination folder, select the System directory option.

6. Now click OK.

The ActiveX component has now been added to Visual Installer’s file list. It will be automatically registered during the setup process. Registration is an important part when installing ActiveX components, and Visual Installer will do it for you.

Sometimes ActiveX are dependent on DLL files
Mostly ActiveX files can be distributed alone, but sometimes they are dependent on additional DLL files. If you add an ActiveX file manually (as described above) and you get problems in another computers when running your application, you should check the documentation for the ActiveX, if also DLL files must be distributed in the same time. You can add the DLLs to the file list in the same way as described above. The destination directory for the DLL file must be the same as the ActiveX file.

How to copy/move many files at once in Visual Installer’s script language

There is a built-in script language available in Visual Installer. The script language is very versatile and with the script commands you can do different kind of file operations and other types of operations during an installation.

File copy operation One common operation is to copy or move files during an installation. There are commands available in Visual Installer’s script language that can do this. If you need to copy or move many files at once, you can use the MCOPY and MMOVE commands for this purpose. Below is the syntax of these two commands described:

MCOPY %Source, %DestinationDir
Copies many files at once. %Source specifies the source file path and %DestinationDir specifies the destination folder for the files.

MMOVE %Source, %DestinationDir
Moves many files at once. %Source specifies the source file path and %DestinationDir specifies the destination folder for the files.

You can use wildcards with the %Source parameter. Example: “%DESTDIR\Data\*.txt”. The code examples below show how to use these two commands with wildcards etc.:

Example 1 – Copy many files at once
Copies all files in the %DESTDIR\Data folder to the %DESTDIR\NewPlace folder:

MCOPY %DESTDIR\Data\*.*, %DESTDIR\NewPlace

Example 2 – Move many files at once
Moves all text files in the %DESTDIR\Data folder to the %DESTDIR\NewPlace folder:

MMOVE %DESTDIR\Data\*.txt, %DESTDIR\NewPlace

To add script commands to an installation, you need to open the Special – Execute script commands menu item in Visual Installer’s editor. More information is available in this tip.
