XCLN: Setup Could Not Write to File Mapiform.vbx (158010)


The information in this article applies to:

  • Microsoft Exchange Client 4.0
  • Microsoft Exchange Windows NT client 4.0
This article was previously published under Q158010

SYMPTOMS

After you use the Chess form and you quit and log off the client, if you run the Microsoft Exchange client Setup, the following error message may appear:
Setup could not write to file: "c:\win95\system\mapiform.vbx" This file is currently being used by another application. Close any open applications.

CAUSE

Mapiform.vbx should be unloaded after you have quit the Microsoft Exchange client and closed all messages and executable files, but Chess.exe is not unloaded when you quit and log off the client. Therefore, Mapiform.vbx and Mapi.dll remain loaded in memory and affect Setup when it tries to update or remove them. This only occurs with the Chess form.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
