DeadlineClient installer issues on Windows 11

Hello,

I’m having difficulties running “DeadlineClient-10.1.23.6-windows-installer.exe” on two Windows 11 hosts.

These are my options in PowerShell :

&$deadlineInstallerPath --mode unattended --connectiontype Repository --slavestartup true --repositorydir $repo --debugtrace $deadlineDebugTrace

I have used the same options for deploying and redeploying countless hosts on Windows 10 in the past without any issue whatsoever

The first time I run the installer in PowerShell, the error message is :

T h e r e   h a s   b e e n   a n   e r r o r .   A   d e b u g   f i l e   h a s   b e e n   c r e a t e d   a t : 
 C : / U s e r s / R E N D E R ~ 1 / A p p D a t a / L o c a l / T e m p / b i t r o c k _ d e b u g . x m l 
 P l e a s e   a t t a c h   i t   t o   a n y   b u g   r e p o r t . 
 T h e   a p p l i c a t i o n   w i l l   e x i t   n o w . 

The second time :

T h e r e   h a s   b e e n   a n   e r r o r . 
 U n k n o w n   e r r o r   l o a d i n g   p r o j e c t 

If I double click on the .exe I think I have seen references to an “unkown tag” in “DeadlineClient-10.1.23.6-windows-installer.exe\project.xml” but the error window disappear too fast so I’m not sure and now this error window won’t appear anymore.

This is a brand new Windows install (clean install via USB after formatting the C drive).

Please find attached bitrock.debug.xml :

Thank you

I now have the third error message about an unkown tag :

T h e r e   h a s   b e e n   a n   e r r o r .
