Runtime Error 52: Bad Filename or Number [Fix]

When initiating an FRx installation that directs to a network SysData directory, this error 52: Bad filename or number may occur. Other workstations can also encounter this error; however, it is not always the case.

Switching to a local SysData directory resolves the issue, and the error message is no longer received. The matter at hand resembles the Runtime Error 217, which we have addressed in a previous guide.

Before we take any steps to address the issue at hand, we must examine its underlying cause.

What is Microsoft Runtime error 52?

This error occurs in Visual Basic applications, and the most common causes are the following:

• Invalid file name – In case the file name is invalid, the code won’t be able to run, and you’ll get this error.
• Unspecified file – If the file isn’t specified properly or if it’s closed, you’ll get this error message.
• Out-of-range file numbers – Sometimes, a code might generate numbers that aren’t valid, thus causing this error to occur.

How can I fix Runtime error 52: Bad filename or number?
