Software Deployment

I can't imagine that the app is shown twice on one install so I figure what you're saying is that the original appears in ARP as well as yours. In that case, the two apps have different Product Codes. Either edit your package so its PC matches the original and update/upgrade/whatever or use your package to uninstall the original (using its Product Code as the argument to MSIExec). I guess the latter is preferable since, as you say, the original is 'screwed'.

Thanks for replying, but its a one install. I am manualy installing (ProCalc17.msi) on a clean machine to see the appln, it shows twice in add/rem prog. I chked the regsitry enrty i coudn't find anything.
Help.

Sounds like there is either a Registry table entry using the Key under
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
" or some where under "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Management"

Sometimes the aftermarket deployment tools you use will add an entry also, might be worth checking that.
