Hi all,
I was trying to do In place upgrade for MS CRM 2013 on my test server and I was getting following errors1. Setup asking for Reboot even after couple of restarts.“Error| Setup cannot continue because there is a pending restart required. Restart the computer and then try running Setup again.”


I went through Error Log located @ C:Users<User>AppDataRoamingMicrosoftMSCRMLogs


Following is the error log which says SkyDrive requires an uninstall. Even after uninstalling Skydrive explicitly the problem persists.

03:40:11|  Error| Reboot required — Key Found: HKCUSoftwareMicrosoftWindowsCurrentVersionRunOnce contains Uninstall C:UsersAdministratorAppDataLocalMicrosoftSkyDrive16.4.6010.0727
03:40:14|  Error| Setup cannot continue because there is a pending restart required. Restart the computer and then try running Setup again., Error, OK

03:40:14|   Info| InputResult: OK


Solution:
Following Support Article helped resolving the issue. Article talks about “MS CRM for Outlook” installation. However, this applies to MS CRM installation also.
We just need to remove registry keys mentioned under the specified registry hive. This resolves the problem.

2. Setup System check fails as the selected CRM 2011 organization for upgrade is using CRM 4.0 end points in web resources.

Solution:
We need to upgrade legacy code first in order to do the installation. So, it looks like Microsoft made it mandatory for the code upgrade from unsupported code(may be not every unsupported code). As it is a test server(Lazy enough to find an excuse), I have opted a Vanilla CRM Organization for the upgrade.

Hope it helps…!!! 🙂
