Prepare Install Command, Unisntall Command and Product Code

I’ll deploy a jre exe application.

For any exe applications, we need to have 3 things:

Install command: Unlike msi file, exe’s install command is uncertain. For the jre exe, I need to go to the java website to check what is the install command.
Uninstall command
Detection method

Found Java install command here: https://www.java.com/en/download/help/silent_install.html

Test the command installation first:

So the install command line is:

jre-8u301-windows-i586.exe /s

Uninstall command:

For uninstall command, we need to get the uninstall string. To obtain the uninstall string of any application from the registry:

Open the registry
Browse:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
This is the location where all the 64 bit application registers itself in registry. You will need to find the required application in the list.
In the right hand pane select either 'uninstallstring' or 'quietuninstallstring' and copy the contents of the 'Value Data' feild.

I right clicked Uninstall and searched “java”, nothing helpful showed. After some searching on java website, I found this article:

https://www.java.com/en/download/help/regkey_addremove.html

So I searched “Java 8” with capitalized “J” and this time I found the uninstall string. Later on I tried “Java” and could also find it. It’s in this location:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\

Copy its value data:

MsiExec.exe /X{26A24AE4-039D-4CA4-87B4-2F32180301F0}

For its uninstall command, we need to put a space after “/X” and add “ /q” at the end of the string, which means “uninstall silently”. Note that there’s also a space for it; so it’d be like:

MsiExec.exe /X {26A24AE4-039D-4CA4-87B4-2F32180301F0} /q
