Jul 12, 2017  Have you tried to install a program in Windows 7 that uses an MSI file as its installer and instead you saw the above error? There is an easy solution and we’re here to help you with it.

I have the VMWare MSI ' failed issue. Unfortunately this question does not have an answer yet.

I'm stuck at step 4 of the official VMWare troubleshouting website regarding this issue

Basically it says

Run the installer of the currently installed version of Windows installer [original text 'Workstation' seems to be wrong] and choose Repair

However, when I follow the link, it only brings me to Windows Installer Redistributables for Version 4.5. Windows 7 needs Windows Installer 5.0. Microsoft says:

There is no redistributable for Windows Installer 5.0

I have also tried

Start Windows Installer Service
Run MSIExec /UNREGISTER
Run MSIExec /REGSERVER
regsvr32.exe /s %windir%system32msi.dll

How can I repair Windows Installer 5.0?

Versions:
Windows 7 SP1 x 64
old VMWare Workstation 8.0.6
trying to install new VMWare Workstation 10

Have you tried to install a program in Windows 7 that uses an MSI file as its installer and instead you saw the above error? Never fear. There is an easy solution and we’re here to help you with it.

First, click on the Start menu and select Run.

NOTE: If you don’t see the Run command on the Start menu, see our article about adding the Run command to the Start menu.

In the Open edit box on the Run dialog box, enter “cmd” (without the quotes) and click OK.

The Command Prompt window displays. For 64-bit Windows, type the following at the prompt and press Enter.

%windir%system32msiexec.exe /unregister

This unregisters the msiexec.exe file in the C:Windowssystem32 directory.

NOTE: We will show you the commands to enter for 32-bit Windows at the end of the article.

Type the following at the prompt and press Enter.

%windir%system32msiexec.exe /regserver

This re-registers the msiexec.exe file in the C:Windowssystem32 directory.

Type the following at the prompt and press Enter.

%windir%syswow64msiexec.exe /unregister

This unregisters the msiexec.exe file in the C:Windowssyswow64 directory.

Type the following at the prompt and press Enter.

%windir%syswow64msiexec.exe /regserver

This re-registers the msiexec.exe file in the C:Windowssyswow64 directory.

To close the Command Prompt window, type “exit” (without the quotes) at the prompt and press Enter.

Reboot your computer. You should now be able to install programs that use MSI installer files.

To fix this problem in 32-bit Windows, open the Command Prompt window as described above. Type the following commands in order, pressing Enter after each:

msiexec /unregister

msiexec /regserver

Exit the Command Prompt window and reboot your computer to complete the fix.
