Unable to load dsr files in vb6 project

Question

I am currently trying to open up an old project that I have in my possession. Its written in vb6 and I have attempted to upgrade to a newer version but I get a slew of errors saying I need to have a working vb6 environment with all references in order to upgrade.

I have vb6 itself working and when I open my project file any .dsr, .dsx files will not load with the following error (which prompts me to go to the log file).

Line 2: Class {BD4B4E61-F7B8-11D0-964D-00A0C9273C2A} of control crBooking was not a loaded control class. Line 0: The file C:\Users\Greg\Desktop\VB6 - Conversion\VBSource\crBooking2.Dsr could not be loaded.

All form files along with class modules and the project file itself load just fine. I have no idea what this means or how to fix it. Any help would be greatly appreciated.

Answer 1

The .dsr files are generated by any so called Designer. Those are extensions which can be added to the VB6 environment. On example is the Designer which is used by the Visual Basic for Applications IDE extension. This one is used, if you are developing an extension for VB6 or VBA itself.

As already mentioned, the GUID seems to belong to a Crystal Reports component. So it might be necessary to either install a greater version of VB6 (some of them come with a Crystal Reports light) or to install the Crystal Reports software itself.
