Hello,
Run the following commands from a command prompt:
1. msiexec /unregister
2. msiexec /regserver
If this fails to resolve the issue, try performing the following procedure to reinstall the installer service:
1. Unregister Windows Installer: msiexec /unregister
2. Rename the following files from the command prompt:Msi.dll, Msiexec.exe, and Msihnd.dll
(Change the names to msi.dll.bak, msiexec.exe.bak and msind.dll.bak respectively)
3. Restart Windows
4. Install the Windows Installer service again (InstMSI.exe) from the Backup Exec Software CD (PATH= Build\Winnt\Install\BE\InstMSI.exe)
OR download from the Microsoft Web site ( http://www.microsoft.com )
The Installation Wizard should open successfully after the installation is complete.
