WiX RegistrySearch in all subdirectories

Question

I need to check whether an any version of some product is already installed.

<RegistrySearch Id="MyId"
                  Root="HKLM"
                  Key="SOFTWARE\Company\{ANY FOLDER}"
                  Name="MY_KEY_NAME"
                  Type="file"  />

Is it possible to use RegistrySearch for searching in all subdirectories?

Thanks guys! I used the custom action as was described here: [http://stackoverflow.com/a/1340107][1] [1]: http://stackoverflow.com/a/1340107 — Viktor, Jul 25 '14 at 10:58

To my knowledge and from the documentation I see nothing that points to RegistrySearch recursing through directories. To do that you'd need to use a custom action. Another possibility and one we used on an installer was to search on the UpGradeCode e.g.

 <Upgrade Id ="other product's guid">
  <UpgradeVersion OnlyDetect="yes" Minimum="0.0.0.0" Property="OTHERPRODUCTDETECTED" IncludeMinimum="yes" />
 </Upgrade>

You would need a block such as this for every product you are attempting to search for, which requires knowing all the guids.

AppSearch / RegLocator doesn't support recursion. You'll either need a custom action or change the way you store data in the registry.
