Custom registry data not working

Hello

I have some problems with custom registry data on LDMS 9.5 and Windows 7 64bits clients : data are not insered into database.

Clients ldappl3.ini are up to date and "Unknow items" is configured to allow my custom data, following http://community.landesk.com/support/docs/DOC-7457

Inventory is launched using "C:\Program Files (x86)\LANDesk\LDClient\LDIScn32.EXE" /NTT=LDMSSRV:5007 /S=LDMSSRV /I=\\LDMSSRV\ldlogon\ldappl3.ldz /NOUI"

Even Internet Explorer version registry is not working, after applying http://community.landesk.com/support/docs/DOC-27801

I have also tried to clean database using DBRepair (06022011)

If you have an idea, I'm your man

Regards

Eric
