Need help with FileSite v9.3 64bit integration

Hi all, I think I need some assistance with FileSite and Acrobat integration please. 

On two reference cpmputers, I first installed Acrobat then followed by FileSite. The "iManage" menu does not show up. 

Windows 10 Enterprise 64bit 22H2
Adobe Acrobat (64-bit) v22.003.20282 (Named user license)
iManage Work FileSite (x64) v9.3.6.807

1. FileSite installs the integration api file in
   C:\Program Files\Adobe\Acrobat DC\Acrobat\plug_ins\IManAcrobat10.api
   C:\Program Files\Interwoven\WorkSite\Win32\1033\iManAcrobatRes.dll
   
   
2.  In Adobe, I disabled "Protected Mode at startup" by adding reg entry
   HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown
   bProtectedMode = 0
   
   
3. I Tried adding IManAcrobat10.api in folder "C:\Program Files\Adobe\Acrobat DC\Acrobat\plug_ins\interwoven", but it did not help
   
   
4.  Adobe installation package was generated from the Adobe admin portal. I tried Acrobat customization wizard to load the msi file but it said it was not a valid package. I guess the wizard is not for named user licenses? 

Thanks in advance
