When I attempt to use QuickBooks in a multi-user mode, I am experiencing QuickBooks error H202. This error code is the most technical error that is taking place on a different computer system. I am facing difficulties to open a company file located on another computer system, so I want to eliminate this error code permanently. This accounting problem is stopping me to access the QuickBooks in the multi-user mode. Really, I don’t have the real reasons for it, hence I look for the permanent solutions for it. So I am asking from anyone to share the easiest solutions for this error code.
