Conditionally include folders in Inno Setup

I'm trying to create an installer with Inno Setup that will statically include a folder if it exists. This folder will be installed on the user system if a specific directory already exists on the user's system.

For example, there are configurations specific to 2017, 2018, 2019. If I have a CC2017 folder, then include it in the installer. The installer will put the folder on the user's system in their 2017 folder if it exists.

I use variables to define some of the path and have formatted them without brackets based on the answer here.

#ifexist projpath + "\" + reponame + "\Plug-Ins\Windows\CC2017\"  
Source: "{#projpath}\{#reponame}\Plug-Ins\Windows\CC2017\{#pluginname}\*"; \
  DestDir: "{sd}\Program Files\Adobe\Adobe InDesign CC 2017\Plug-Ins\{#pluginname}"; \
  Flags: ignoreversion recursesubdirs createallsubdirs replacesameversion; \
  Check: MyDirCheck(ExpandConstant('{sd}\Program Files\Adobe\Adobe InDesign CC 2017'))  
#endif

I know it isn't checking correctly because the file size is much smaller when I add the ifexist directives. The Inno Setup docs mention "files" but not folders so I'm suspicious that it might not support checking folders.

What is wrong with the syntax?

I'm using Inno Setup 6.0.2 on Mac 10.13.6

There are two options:

  1. Use skipifsourcedoesntexist flag:

    [Files]
Source: "folder\*"; DestDir: "{app}"; Flags: skipifsourcedoesntexist

  2. Use #if preprocessor directive along with DirExists preprocessor function:

    [Files]
#if DirExists("folder")
Source: "folder\*"; DestDir: "{app}"
#endif
