windows installer - WiX and ARPINSTALLLOCATION -

-

i want msi package write value installlocation hkey_local_machine\software\\(wow6432node)\microsoft\windows\currentversion\uninstall\\(guid). should see value in add/remove programs control panel (column location).

to set value via wix, read property arpinstalllocation should set custom action. reduced <product> minimum. how looks like:

<?xml version="1.0" encoding="utf-8"?> <wix xmlns="http://schemas.microsoft.com/wix/2006/wi"      xmlns:util="http://schemas.microsoft.com/wix/utilextension">   <product id="*"             name="myapplication"            language="1033"             version="!(bind.fileversion.myapplication.exe)"             manufacturer="me"            upgradecode="db37f5dc-68c5-46ee-bbdf-704ff68b70db">     <package installerversion="400" compressed="yes" installscope="permachine" languages="0" />     <majorupgrade downgradeerrormessage="a newer version of [productname] installed." />      <!-- use setproperty suggested rolo -->     <setproperty id="arpinstalllocation" value="[installdir]" after="costfinalize" />     <feature id="productfeature" title="myapplication" level="1">       <componentgroupref id="myapplication.files.allrequired" />     </feature>   </product>   <fragment>     <directory id="targetdir" name="sourcedir">       <directory id="programfilesfolder">         <directory id="installdir" name="myapplication" />       </directory>     </directory>   </fragment>   <fragment>     <componentgroup id="myapplication.files.allrequired">       <component id="productcomponent"                   guid="90ea8f1c-77d2-40e1-81ad-44b076efab9d"                   directory="installdir">         <file id="myapplication.exe" source="$(var.myapplication.targetdir)\myapplication.exe" />       </component>     </componentgroup>   </fragment> </wix>

the msi bundled within wix standard bootstrapper.

you should execute custom action in both sequences (installexecutesequence , installuisequence) , sequence after costfinalize.

you can simplify using this:

<setproperty id="arpinstalllocation" value="[installdir]" after="costfinalize" />
