Hi,
I write to you again to tell you that I solved the "SiDiaryHIDDriverCheck.dll not found" error.
I found in the Windows event logger that errors like this one
"Failed to generate activation context for "C: \ Program Files (x86) \ SINOVO \ SiDiary6 \ MeterDriver \ SiDiaryHIDDriverCheck.dll". Cannot find dependent assembly Microsoft.VC90.MFC, processorArchitecture = "x86", publicKeyToken = "1fc8b3b9a1e18e3b", type = "win32", version = "9.0.21022.8". Use sxstrace.exe to get a detailed diagnosis."
have been logged every time I'd tried to import data in SiDiary.
So I downloaded and installed the "Microsoft Visual C++ 2008 Redistributable x86" and now, after a system update and a reboot, I am able to directly import data from the BM55.
