You get the following error message when installing CRM 2011 server with Network Load Balance.
You are installing CRM 2011 in Network Load Balance. Installation in 1st node went fine but while doing the installation in the 2nd node you get the below error message on the Installation Wizard:
Following are the two possible causes of this error message:
- We are doing installation in 2nd node of CRM 2011 by using the license key from the CRM Config Database. It’s thinking that we are tweaking the CRM Database and is a forge installation and hence stopping from going ahead.
- A recent update roll up or a hot fix has been applied to the 1st node and Use Microsoft update when I check for updates (recommended) radio button is not selected on Select Microsoft Update Preference screen of the installation wizard. You may verify this by capturing the Troubleshooting file for support from the 1st node (where installation is successful) using CRM 2011 Diag Tool: http://crmdiagtool2011.codeplex.com/ look for the recently applied update roll ups and hot fix.
Reboot the 2nd node (where installation is failing).
Add the IgnoreChecks registry key to the computer that is running Microsoft Dynamics CRM so the installation can proceed when an error is shown in the Environmental Diagnostic Wizard (EDW):
Click Start, click Run, type regedit, and then click OK.
In the registry, locate the following subkey:
Right-click MSCRM, point to New, click DWORD Value, and then type IgnoreChecks.
Double-click IgnoreChecks, and then type 1 in the Value data field.
- Make a backup of the registry keys because serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system.
- You need to manually add the MSCRM folder if not already existing after following the registry hive till HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Run setup again in 2nd node(where installation is failing), Use Microsoft update when I check for updates(recommended) radio button. You will need an outbound internet connection on the server to download these updates. With these updates, the installing server version will be greater than the CRM database version and you should be able to proceed.
Note: After including this registry value you will get the same error message in installation wizard but this will also enable the Next> button in Installation Wizard to complete this installation.
