Unable to Install New Software in Windows 95

 Last reviewed: April 4, 1996

The information in this article applies to:
  • Microsoft Windows 95

SYMPTOMS

When you are installing new software in Windows 95, if you use the Close Program dialog box to end the Copying Files or Inserting Disk task, you may not be able to install any new software. If you try to install new software, you may receive the following error message: 

   Rundll32: An error has occurred in your program. To keep working
   anyway click Ignore and save your work in a new file. To quit this
   program click Close. You will lose information you entered since your
   last Save.
In some cases, the Install Program Wizard may seem to work, but the software is not actually installed. You do not receive any error message when this occurs.

CAUSE

When you end the Copying Files or Inserting Disk task, Windows 95 unloads Rundll32.exe from memory, leaving Setupx.dll in memory. Setupx.dll cannot be unloaded properly by Rundll32.exe because Rundll32.exe has already been unloaded.

Note that similar situations can occur adding new hardware with the Add New Hardware Wizard.

RESOLUTION

To resolve this issue, restart Windows 95 and then install the new software.
