Dear Ertuğrul,

it's simple. The 1C process does not have rights to access the directory: C:\Program Files(x86)\1cv8\common\ - that's why this error occurs.

Please try it like this:

TempFileName = GetTempFileName();
BinaryData = SelectionDetailRecords.ref.HSY_Resim1.Get();
BinaryData.Write(TempFileName);
