如何使用Inno Setup查找HKLM子文件夹的名称？

Question

I wish to install an After Effects plugin on the end-users' system. To ascertain the location of installation, I must find out which version, or versions of After Effects are installed. Because the folder structure looks like this:

HKLM/SOFTWARE/Adobe/After Effects/(version)/key

It's not very simple. Most graphic designers install more than one version of After Effects. And I must present them with all of them in order to let them choose which version they with to install the plugin on.

Conversely, I wish to present the user with three options:

1. A key that contains the common install path
2. A key that contains the main install path
3. A custom path

How's that going to be possible given the abilities and limitations of Inno Setup?

Thanks.

You need to know which version is installed on the end user's PC.

It's a piece of cake. :-)

Look at "HKEY_CLASSES_ROOT.aep": It will rewrite every time the installation is executed. So you know the latest version.

For example, it is 4.0 version when the value of "HKEY_CLASSES_ROOT.aep" is "aftereffects.project.40". And then you can check out "HKEY_CLASSES_ROOT\\AfterEffects.Project.40\\shell\\open\\command". There is the installation path.

That's it.
