This potential CRM error should typically appear if you had a CRM database, uninstalled it and then tried to reinstall with a different license type. But it can also appear if you used a different license code during the reinstall. You can get confused if you have access to multiple installations and forgot the key you used for a particular instance. But no worries, you can find you key again in SQL -> MSCRM_CONFIG -> ConfigSettings -> LicenseKey. Use that key and it should solve your problem

CRM Workflows Don’t Work, E-mails Don’t Send…
Symptom: You choose to run a workflow but nothing seems to happen and the new workflow doesn’t appear in the workflow tab.
Theory: If my CRM exam studyage served me right, the Microsoft Dynamics CRM is composed of 3 parts. The application layer producing the business logic, the data layer interfacing with SQL and the async service layer doing stuff like workflows on the background (a bit like SQL agent). If the first 2 break, you won’t get your CRM site at all. When the async service layer breaks, it’s a bit more subtle like in this case. Continue reading
DataGridView Change Cell Data Type After Binding
I don’t know actually since most of the relevant stuff becomes read-only after filling with data. But my approach is solve this as early on in the process as possible to the entirety of the data and save processing time on a custom loop after.
In other words, your DataGridView is typically bound to a DataTable. That is typically filled with stuff from the database. Make sure your AutoGenerateColumns property is set to true in the DataGridView and select your data to match the type you want to display in the DataGridView. For instance, to get checkboxes,
SELECT ..., CAST(column1 AS bit), ... FROM ...
and change the data type right out of the DataAdapter and DataGridView will figure out the rest automatically
Exclude Views in INFORMATION_SCHEMA
Another quick tip.
Selecting from INFORMATION_SCHEMA.COLUMNS unfortunately returns also every column in views on top of tables. I never use views and definitely don’t need those columns.
To filter them out, use:
SELECT * FROM INFORMATION_SCHEMA.COLUMNS c JOING INFORMATION.TABLES t ON c.TABLE_NAME = t.TABLE_NAME AND t.TABLE_TYPE = 'BASE TABLE'
.NET Compare 2 Datarows by Value Using LINQ
There are too many top Google search results giving the impression that it is impossible to compare 2 DataRows for its value contents and the programmer needs to iterate through everything himself.
Such is no longer true in .NET 3.5 but the blogosphere doesn’t seem to have caught on yet.
It is possible, given 2 DataTables or any other enumerable object types, to compare its contents using LINQ in just one line of code.
I will give an example in VB where I’d want to compare all column properties (description, data type, field length, etc) of all tables in 2 supposedly identical SQL databases. Continue reading
SQL Server Check User Permissions
Another quick solution for users of MSSQL Server. 
To view the permissions the current logged SQL user has, use the command
SELECT * FROM fn_my_permissions(NULL, 'DATABASE')
or variations to return a list of SQL commands permitted.
