sqlschemacompare on Visual studio 2012

Question

When I try to compare my database project to an existing database it displays the following error:

The write operation failed. You must first acquire write access from DataSchemaModelController. E:\\SRC SF\\LIBRIDB\\TePuna.scmp

Sql Server Version is 2012 Dev Edition

This happened after I reinstalled visual studio and sql server.

I have also installed SQL Server Data Tools 2012.

I searched with the same error on google but found nothing.

Any help is appreciated.

Answer 1

Update - if you double-click on the new installer and then select "Repair" it will install correctly and you can do schema compares. The SSDT installer for VS2012 does not suffer from this problem - it seems to be confined to the VS2010 installer

Answer 2

I got this error when I upgraded a set of DevExpress controls. I shutdown the IDE and restarted. Everything worked fine afterwards.
