I have just upgraded to DotConnect for SQLite 4.2.77 from a previous version (sorry, can't remember the version). In VB Express 2010, I have successfully gone through the manual installation of components as described in Help. However, when I open projects previously created, I get dozens of errors listed wherever the DotConnect code is used and I can't get further than the page headed "To prevent possible data loss before loading the designer, the following errors must be resolved:". I also have Visual Studio 2012 for Desktop Applications installed, where I get a similar result. Any ideas as to how I can solve the problem?

Thanks in advance.

Please remove the references to the assemblies from the previous version of dotConnect for SQLite and re-add the references to the assemblies from dotConnect for SQLite 4.2.77, rebuild the project and try to re-open the form designer.

If this doesn't help, specify the exact texts of the errors which "must be resolved".

Thanks for your reply.

I removed all references to the assemblies in VB Express 2010 and then re-added them. Unfortunately, the result is the same as before.

Thanks again,

I hadn't previously tried rebuilding the project, so I did as you suggested and received the following error messages after building:

If I then close the project and re-open, I get the same errors as before. As you say, for some reason VB Express can't find the assemblies.

Could not locate the assembly "Devart.Data, Version=5.0.313.0...
Could not locate the assembly "Devart.Data.SQLite, Version=3.50.214.0...

These errors say that there are references to the assemblies from the old (3.50.214.0) version of dotConnect for SQLite instead of the new one (4.2.77.0) in your application. Send us your project so that we can reproduce the issue in our environment.
