How to Switch the Scope Between the perUser to perMachine in Wix toolset V5, as per the User Selected Install Path.

[S09Joshi]

I am using the latest version of Wix toolset (version -5), Using the Bootstrapper Application project to chain all my MSI files and
I have Created my own Custom UI using WPF and Allowing the User to Select the Installation Path and that path I will be setting to my Directory. Like this -

<Directory Id="USERDIRFOLDER">
<Directory Id="INSTALLFOLDER" Name="!(bind.Property.Manufacturer)">
  <Directory Id="MIFolder" Name="!(bind.Property.ProductName)" />
</Directory>
</Directory>

now I want to change the scope of my project based on user selected path, If User Select the path which required the ADMIN ACCESS I want to change my scope to perMachine so that UAC prompt will appear which will asked for Admin USERNAME and Password, Otherwise I want to keep the scope to perUser.
I have tried to use the scope as "perUserOrMachine" in my project and Setting value of MSIINSTALLPERUSER to empty or 1 based on the value of property INSTALLSCOPE value which will be update based to user selected install path.
Here is the code where I am updating the value of MSIINSTALLPERUSER :-

 <!--Check the INSTALLSCOPE property and adjust scope accordingly-->
 <InstallExecuteSequence>
   <Custom Action="SetPerMachine" Before="InstallInitialize" Condition="INSTALLSCOPE = perMachine"></Custom>
   <Custom Action="SetPerUser" Before="InstallInitialize" Condition="INSTALLSCOPE = perUser"></Custom>
 </InstallExecuteSequence>

 <CustomAction Id="SetPerMachine" Property="MSIINSTALLPERUSER" Value="" />
 <CustomAction Id="SetPerUser" Property="MSIINSTALLPERUSER" Value="1" />

But Every time during the installation I can check in my log that the Condition is set to False, so my scope value is never changed.

Action start 09:54:58: RemoveExistingProducts.

Is the approach I am using is correct? - If not, then what are the other alternative WIX provide.

Below the Complete file codes -
Bootstrapper - Bundle.wxs File which contains the MSI file name PermanentPackage which have the MSI Property Name INSTALLSCOPE value. Currently I have not decided how will I change the property value based on user selected path, therefore keeping the default value as perMachine.

`

<BootstrapperApplication SourceFile="$(var.CustomUI2.TargetDir)CustomUI2.exe"> 
  <Payload SourceFile="$(var.CustomUI2.TargetDir)CustomUI2.deps.json" />
	  <Payload SourceFile="$(var.CustomUI2.TargetDir)CustomUI2.dll" />
	  <Payload SourceFile="$(var.CustomUI2.TargetDir)CustomUI2.runtimeconfig.json" />
	  <Payload SourceFile="$(var.CustomUI2.TargetDir)mbanative.dll" />
	  <Payload SourceFile="$(var.CustomUI2.TargetDir)WixToolset.BootstrapperApplicationApi.dll" />
	  <Payload SourceFile="$(var.CustomUI2.TargetDir)Prism.dll" />

  </BootstrapperApplication>

<Variable Name="InstallScope" Value="perMachine"/>

<!--User Selected Folder Property-->
<Variable Name="InstallFolderDir" bal:Overridable="yes" Type="formatted" Value="[LocalAppDataFolder]" />

  <Chain ParallelCache="yes">

  <!-- Add the Package to be bundle -->
  <!--<PackageGroupRef Id="NetFx48" />-->

  <MsiPackage Id="PermanentPackage" Cache="keep" Visible="no" SourceFile="W:\Work\Project\Host\bin\PermanentProject.msi" Compressed="no" 
              DownloadUrl="$(var.URL)/PermanentProject.msi">
	  <MsiProperty Name="USERDIRFOLDER" Value="[InstallFolderDir]" />
  <MsiProperty Name="INSTALLSCOPE" Value="[InstallScope]"/>
  </MsiPackage>

</Chain>

Here is the PermanentPackage Product.wxs File -:

`

<MajorUpgrade DowngradeErrorMessage="$(var.DowngradeErrorMsg)" />

<MediaTemplate EmbedCab="yes" />

<Feature Id="ProductFeature" Title="PermanentProject" Level="1">
  <ComponentGroupRef Id="ProductComponents" />
  <ComponentGroupRef Id="RemoveComponents" />
</Feature>

<!--Check the INSTALLSCOPE property and adjust scope accordingly-->
<InstallExecuteSequence>
  <Custom Action="SetPerMachine" Before="InstallInitialize" Condition="INSTALLSCOPE = perMachine"></Custom>
  <Custom Action="SetPerUser" Before="InstallInitialize" Condition="INSTALLSCOPE = perUser"></Custom>
</InstallExecuteSequence>

<CustomAction Id="SetPerMachine" Property="MSIINSTALLPERUSER" Value="" />
<CustomAction Id="SetPerUser" Property="MSIINSTALLPERUSER" Value="1" />


<Directory Id="USERDIRFOLDER">
  <Directory Id="INSTALLFOLDER" Name="!(bind.Property.Manufacturer)">
    <Directory Id="MIFolder" Name="!(bind.Property.ProductName)" />
  </Directory>
</Directory>
<StandardDirectory Id="DesktopFolder" />
<StandardDirectory Id="ProgramMenuFolder">
  <Directory Id="ProgramMenuDir" Name="!(bind.Property.ProductName)" />
</StandardDirectory>

Also, I need to ask if I keep my Directory to LocalAppDataFolder (any Folder Directory which doesn't required privileges) not allowing user to select the installation path and in case user doesn't have the sufficient space then how can I counter this issue.
I know If I do not have sufficient space then installation will fail but is there any backup storage space/folder we can provide to user in case in-sufficient space.
