SqlCeException was unhandled
The operating system does not support the encryption mode provided.

The environment is:
  • Windows 7 Home Premium
  • Visual Studio 2008
  • .Net Framework v3.5, SQL Compact v3.5

Reason: 193(failed to retrieve text for this error. Reason: 15100). SQL: INSERT INTO [#$ndo$groups] {CALL [master]..[xp_ndo_enumusergroups](?,?)} The reason for this error is that the installed xp_ndo.dll is 32 bit and not 64 bit. My solution was simple to replace xp_ndo.dll with the 64 bit version. 1. Stop SQL server 2. Copy \\vedfssrv01\DynamicsNAV2009\W1\DVD\Sql_esp\x64\ xp_ndo_x64.dll to C:\Program Files (x86)\Microsoft Dynamics NAV\60\Database 3. Rename existing xp_ndo.dll to xp_ndo_x32.dll 4. Rename xp
