Error Reinstalling CRM 4.0

The following error occurred when trying to reinstall MS Dynamics CRM 4.0. The problem is that the uninstall process of CRM does not make a complete removal of all the security principals from the system.



In order to make a proper uninstall of Microsoft Dynamics CRM 4.0 product, I followed the steps below:


1. I made the uninstall of all crm products from add/remove programs


2. I deleted all contents of crm directory. Mine was ‘C:\Program Files\Microsoft Dynamics CRM’


3. From Active Directory I removed all the crm principals




Principals in you deployment may be placed on other folder in Active Directory depending of the installation you have made


4. From Sql Server I made a backup and then a delete of all crm databases (*_MSCRM, *_CONFIG)
5. From Sql Server I removed all the crm principals





6. I deleted CRM registry settings HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM (I had a trace flag on, and a language pack)

After all this I made a brand new installation without any problem.
