Windchill PDMLink 11.1 M010 to M020 - Install Maintenance Release option is grayed out

Hi @MattPat 

It happens always if you try to install a CPS with different windows account then the original Windchill has been installed.

So you need to search for psi_iir_index.xml in the C:\Users\<ACCOUNTUSER>\AppData\Roaming\PTC\Windchill

If the file is missing a PSI installer do not know the actual installation.

Also you can recreate the file. 

File is XML

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE InstallInstances [
 <!ELEMENT InstallInstances (Instance*)>
 <!ELEMENT Instance EMPTY>
 <!ATTLIST Instance id CDATA #REQUIRED>
 <!ATTLIST Instance location CDATA #REQUIRED>
]>

<InstallInstances>
 <!--Registries are located in '[location]\installer\instreg\[id]'-->
 <Instance location="D:\Windchill_11.1\PSI" id="ii7516893e.16faed2c436.-8000"/>
</InstallInstances>

You just need to go to installed PSI folder where you can find the ID 

The ID is in PTCSolnInstaller-installer.properties file (example D:\Windchill_11.1\PSI\installer)

WC_PROMPTED.PSI.SELECTED_UPDATE_INSTANCE= 

in my case> WC_PROMPTED.PSI.SELECTED_UPDATE_INSTANCE=ii-26f8cb9f.16faeed5930.-8000

Hope this can help

I would hope you can convince your client to go to Windchill 12 as Windchill 11.1 is out of support as of January 2022.
