Something like this: <Property Id="PROP1"> <RegistrySearch ... /> </Property> <Property Id="PROP2"> <RegistrySearch ... /> </Property>
<CustomAction Id="SetINSTALLDIR1" Property="INSTALLDIR" Value="[PROP1]" /> <CustomAction Id="SetINSTALLDIR2" Property="INSTALLDIR" Value="[PROP2]" /> <CustomAction Id="PathNotFound" Error="No path was found in the registry." /> <InstallExecuteSequence> <Custom Action="SetINSTALLDIR1" After="Appsearch">PROP1</Custom> <Custom Action="SetINSTALLDIR2" After="SetINSTALLDIR1">NOT PROP1 AND PROP2</Custom> <Custom Action="PathNotFound" After="SetINSTALLDIR2">NOT PROP1 AND NOT PROP2</Custom> </InstallExecuteSequence> Because AppSearch does not guarantee the order of search execution you need to search for both regkeys. If you think you absolutely must look for an alternative key only if first regkey does not exist, you have to do the lookup for alternative key in the custom action scheduled after AppSearch.

Hello, In my installer i want to check if a regkey exists if so assign the value to a property and if the first regkey doesnt exist i need to verify an alternate second regkey and assign the value to the property. I currently i use the following snippet to search the registry to get the value from my first regkey <Property Id="INSTALLDIR" Value="0"><RegistrySearch Id="SERVER_INSTALLDIR_REGSEARCH" Root="HKLM" Key="SOFTWARE\Microsoft\commsvr\v1\Setup" Name="MsiInstallPath" Type="raw" Win64="$(env.TARGET_WIN64)" /></Property> How do i check if the above regkey is not present and look in the alternate regkey "HKLM\SOFTWARE\Microsoft\commsvr\Setup\MsiInstallPath" and assign the value to property "INSTALLDIR" would be really thankful if somebody could tell me how i can accomplish this. thank youKiran Nallabothula.
