OFF2000: Windows Installer Version Error When You Update to SP-2
To determine the version of the Windows Installer that is on your computer, follow these steps:
- Click Start, point to Find, and then click Files or Folders.
- In the Named box, type Msi.dll.
- In the Look in list, select the drive that contains your Windows folder.
- Click Find Now.
- Right-click Msi.dll and then click Properties.
- In the Msi.dll Properties dialog box, click the Version tab.
If the version number for Msi.dll is 1.00.5104.0, you have the Windows Installer 1.0 installed. In this case, you must run the SR-1 update again to update the Windows Installer to version 1.1. If your version of Msi.dll is later than 1.00.5104.0, you do not need to update the Windows Installer.
