Plus DME Update

[Clifford C. Claven]

I hope I dont get yelled at about not searching, cause I did and couldnt find anything helpful, but my problem is I am not sure how to silently install Plus DME Update. It is an exe with a .msp update file inside of it. I searched the web and tried to use the commands I found to update the original msi installer but it says the msi is not capable of being updated that way. I tried to use many simple silent switches and it would start and appear as if it would work but then comes up with an error saying c:\config.msi\PT26.tmp has probably already been updated by other means and can no longer be updated. As always and help on a solution or what is wrong would be greatly appreciated.
