Hi,

Strange problem. I've downloaded MCP build 503f and it won't run on my FSX PC. I get Error 52 - bad filename or number. Never had this problem in 11 years of updates.

But it will run on another desktop and my laptop. All PCs are W7 64-bit. Enrico cannot replicate it. But if the previous version ran fine it suggests a change in how this one was compiled. But what and why does it only refuse to run on my FSX PC?
