If PDF24 is installed using the .exe file from the link below, it does not appear in the condition pop-up. I need it to work with both 32-bit and 64-bit .exe installers:

Re: Not detecting the prerequisites pdf24
Hello,
PDF24-creator is not Windows Installer based. This is the reason why the application is not listed in the drop-down.
Only MSI files have an UpgradeCode (part of Windows Installer technology). An EXE does not and cannot have an Upgrade Code unless it installs or unpacks an MSI internally.
Since you can’t obtain an Upgrade Code here, you’ll need a different detection method. Two common alternatives are:
1. File version check. For example, test that "C:\Program Files\PDF24\pdf24.exe" exists and matches desired version.
2. Registry check. Look for a key such as: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{…}
and verify the DisplayName/DisplayVersion values.
Hope this helps! Let us know if you have any questions.
Best regards,
Liviu

Re: Not detecting the prerequisites pdf24
how can I make it detect both 32-bit and 64-bit PDF24 installers with 32bit installer?
Re: Not detecting the prerequisites pdf24
Hello,
Do you want to deliver both the x32 and the x64 versions of your prerequisite?
If so, add each version and for the 64 one check the "Use 64-bit location when evaluating conditions on a 64-bit machine" option from under the "Conditions" tab.
