Problem:

The normal route of Control Panel > Add or Remove Programs does not show the installed fix packs for Mainframe Express Enterprise Edition, so how can MSI installed fix packs be removed from Windows 2000 & Windows 2000 Server machines?

Resolution:

Down load the fix pack from the web site....in this example Mainframe Express Enterprise Edition 3.1 WS04.

Highlight the file and look into the properties of the file.

Open the SUMMARY tab.

Click on the revision number and this will allow you to cut and paste it, it will look something like -  {996A2582-65B0-4002-B3E5-2232CB9A4564}

Using REGEDIT, navigate to the following registry item...

HKEY_LOCAL_MACHINE/Software/Micro Focus/Cobol/6.0/Setup/ProductCode

Cut and paste the entry for this item, it will look something like -

{1A0B6822-4BBF-4534-A524-BA0D92878C73}

Now construct the command line as follows....

start /wait msiexec /qb /i {1A0B6822-4BBF-4534-A524-BA0D92878C73} MSIPATCHREMOVE={996A2582-65B0-4002-B3E5-2232CB9A4564}

This will remove the fix pack WS04 from the installation of Mainframe Express Enterprise Edition 3.1.
