I recently had my machine rebuilt by our local IT support folks and now I can’t open ActiveReports code files in the designer. I get the following error:
“Value cannot be null. Parameter name: instance”
The designer will open just fine on other developers’ machines. We can’t seem to determine what’s different about mine. The only thing I’ve seen online about it is something about licensing, but we’re all using the same licensing file. This is with ActiveReports version 6.2 and VS2010.
Any ideas anyone?
