ConfigMgr Bug – Stuck At “Preparing computer for first use…”
This was on the MDT/OSD list and I thought I’d post it. There is a known issue if with 64-bit systems where the TS stalls at State Restore when it hits the Use Toolkit package step.
Per Tim Mintner, here is the fix:
Create a “Run command line” step (positioned before the “Use Toolkit Package” step in the new OS) run this command:
reg add HKCR\Wow6432Node\TypeLib\{D5E1749D-832D-4587-AFC3-9462187FE2F5}\1.0\0\win64 /ve /d "%WINDIR%\SysWOW64\CCM\tscore.dll" /f
This will fix the one registry key that we have identified as being incorrect, which causes the MDT scripts (and any other VBScripts that try to use Microsoft.SMS.TSEnvironment) to fail
