1.1.7.7b Exception on program start

[luedi]

I just installed the 1.1.7 Beta. Before doing this i have removed Version 1.1.5 via the uninstaller. Additionally i had removed all entries in the registry which where left by the uninstall manually. When i start MyGeneration i get following exception:

Code: Select all

MyGeneration   1.1.7.7

When i press cancel the GUI is shown. But if i try to call the default settings screen the same exception is thrown again.

I tried to edit the defaultsettings.xml manually but this didn't work.

The COM exception is due to the registering of the MyMeta.dll, there is a post in the \"Registration and Installation Issues\" that shows how to manually register it, you might try that.

Thanks for your help. Sorry that i didn't found the \"Registration and installation issues\" forum by myself . Manually registering MyMeta.dll helped.

As MyGeneration now works with .NET 2.0 i used REGASM of the 2.0er framework. Maybe the error occured because REGASM show some warnings on the command line. Unfortunately i have only german messages. The warnings said that there are generic type instances in a signature which can't be exported to COM for the following methods:

MyMeta.IMyMetaPlugin.GetPrimaryKeyColumns(#0)
MyMeta.IMyMetaPlugin.GetViewSubViews(#0)
MyMeta.IMyMetaPlugin.GetViewSubTables(#0)

On my PC in the office i just installed MyGeneration 1.1.7 over the older Version. Under this circumstances i had no problems. On my laptop i had deinstalled the old version and removed all MyGeneration-related entries in the registry (by searching for MyGeneration and MyMeta).

Ahh, very interesting, I will take a look at these methods and give this a try. I'm glad you're up and running however. I think you've given me enough to track this down ...
