How to check remotely that a PC has been restarted after Labview Runtime 2011 has been installed on it?

Question

Hello,
I am deploying a Labview 2011 application on 150 XP-machines in various plants worldwide. Currently all machines still have an old Labview 8.21 runtime (+old DAQmx). I have sent a procedure to my colleagues in the plants so that they install the new runtime (+ new DAQmx). On my side I have built a code to check from my Pc if a certain registry key is present on the 150 PCs which tells me that the new installer ran or not.
The key that I found is:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Installer\Products\1C5E801AE54C4AE43A59FC169F95CA28]
"ProductName"="NI-DAQmx MAX Configuration Support 9.3.5"
"PackageCode"="61EEAEC207A28A842B3341ED6809453D"
"Language"=dword:00000009
"Version"=dword:0923c001
"Assignment"=dword:00000001
"AdvertiseFlags"=dword:00000184
"InstanceType"=dword:00000000
"AuthorizedLUAApp"=dword:00000000
"Clients"=hex(7):3a,00,00,00,00,00
This works well but it does not tell me that the PC has restarted after the installer has been run. If I do not restart the PC and try to execute my Labview 2011 executable I get a long error message (NIDAQmx not registered,...).
As it seems difficult to get the properties of a key to know when it was installed I was rather leaning towards checking if a certain DLL (?) has been registered or not. But it is just a vague idea and I do not know how to put that in place.
I am attaching the current code that I have and that works well but cannot make the difference between Labview 2011 runtime installed and PC restarted or not.
Thanks for the help

You might look for a file that would be created as part of installation to determine the install date/time (ini or other support file created as part of runtime install)
Combine that with a query of the station's uptime and you could calculate if the station has been up longer than the time since the install. Not perfect, but should be possible...

Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T
