I'm currently seeing the following behaviour when running an In-Place upgrade to Win 10 in my client.msi log.
Client MSI 'This update package could not be opened. Verify that the update package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer update package.' In the ccmsetup.log it is using the following syntax to run the install: MSI PROPERTIES are REINSTALL=ALL REINSTALLMODE=vmous INSTALL="ALL" PATCH="C:\_SMSTASKSEQUENCE\OSD\***00004\HOTFIX\KB2938441\X64\CONFIGMGR2012AC-R2-KB2938441-X64.MSP" SMSSITECODE="***" CCMHTTPPORT="80" CCMHTTPSPORT="443" CCMHTTPSSTATE="224" CCMFIRSTCERT="1" CCMCERTID="SMS;651D68A957E24DB0FDA887EB1494580F1A0ECFC0" REMEDIATE="true" CCMUPDATEOSVERSION="6.4.9841" SMSPUBLICROOTKEY=******** My initial thought is is that it is calling up the patch command issued as part of my Win 7 TS build originally laid down on the machine. The C:\_SMSTASKSEQUENCE\OSD\***00004\HOTFIX\KB2938441\X64\ no longer being available on the endpoint post original O/S build. Is anyone successfully running in-place upgrade with the patch command being used in their original OSD TS? Cheers Paul
