Hello. I have a new pc running Win7. I'm using RS500, 5000, PBuilder, FTVME, RSLinx for Dnet. All these run ok, but when started -via shortcut- rslinx classic gives the tiniest blip on the hard drive light and doesn't run. It's a recent install (this month) when I migrated the others across. I have tried compatibility mode; no change. A look at it in explorer shows 147 files and 8 folders (does this sound right?) It won't run from explorer either. Any ideas appreciated, thanks.
