Body
I have a C#.NET application having some version 1.0.0.1. I did some modifications to my application & want to release it with an upgraded version 1.0.0.2. If the older version 1.0.0.1 is already installed in client's system & if client tries to install the newer version 1.0.0.2, then it is throwing the followin error message <blockquote> Installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2869. </blockquote> Initially after changing the version no:, I had also changed the productCode of the new version. But did not modify the upgrage code in the set up project. Can any one kindly let me know how to fix this error 2869.. Thanks In advance.

1. COError 2869 is about an error dialog "The dialog [2] has the error style bit set, but is not an error dialog"; it is not likely to be the real error. Inspect a verbose log (/l*v setup.log) and look for what action gives return value 3.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
