Invalid Class String

[mikev777]

Hello,

I just re-installed XP, esignal, and Visual C++ on my machine and when I recompiled my Desktop API project, I received the following message:

"Error initialising. Invalid class string"

tracing back through the code, it looks like it's bombing on:

new IHooksPtr("IESignal.Hooks.1");

I added winsig.tlb into the project again (thinking maybe it got removed in the install; how I don't know) and got all these redefinition errors so I took it out.

It's been a while since I installed the Desktop API. Is there something I just forgot?

Problem solved.

After XP was re-installed, I needed to open the esignal application directly first at least once (before I use my Desktop API application) for the Class string to be registered (I guess it does not do that at install).
