I have repeatedly tried rebuilding a Solution in VB.NET (Windows XP OS, Visual Studio .NET 2003), and I keep getting the error/task message "'Property License' Key is non-nullable". The build had worked previously, though it has been a while since I have attempted to do so. I do have the code that was previously successfully built stored in a ZIP file, and I have tried the rebuild from the unzipped code (several unzips). The PC has both Spread for Windows Forms 220.127.116.11 and also 2.5.1007.2002 installed. I had "inherited" this project from an outside developer, who is no longer available.
There is a licenses.licx file in the solution, that has the following text:
FarPoint.Win.Spread.FpSpread, FarPoint.Win.Spread, Version=18.104.22.168, Culture=neutral, PublicKeyToken=327c3516b1b18457
Clicking on the Task ('Property License' Key is non-nullable) in the Task List in VB.NET doesn't lead to anything. I reviewed some of the documentation that came with 22.214.171.124 (Start Menu Program Group) but didn't seem to find much as far as instructions go on how to implement the software. There did seem to be some mention that a license key, or something like that, automatically regenerates itself (or something like that).
When I open the Solution, I also get prompted about upgrading to Crystal Reports 10, but I click No.
Any help is much appreciated. Thanks.
