Software Deployment

ARPSYSTEMCOMPONENT is the property that hides the app from Add/Remove programs.
You could also populate HKLM\software\microsoft\windows\currentversion\uninstall\[productcode]

IIRC, it is the use of ARPSYSTEMCOMPONENT which triggers the WI engine to not write the 'Uninstall\[ProductCode]' registry key.

Anyway, to the actual problem...my guess would be that the package itself is removing that key, either via a Custom Action or via the RemoveRegistry table.

IIRC, it is the use of ARPSYSTEMCOMPONENT which triggers the WI engine to not write the 'Uninstall\[ProdictCode]' registry key.
Almost, if the property is defined WI will write the SystemComponent (DWORD) reg entry with a value of 1 to hide the ARP entry and not prevent the Uninstall\<{ProductCode}> reg key.

Could the package be a InstallShield based one?
Search under the Uninstall key for the product name (ProductName property value)

This package is an Installshied package. Should I convert it to a Wise package?

This package is an Installshied package. Should I convert it to a Wise package? Why would you want to do that? What difference would it make? As I mentioned, the package is likely to be removing the uninstall registry key via a Custom Action, or it could be dynamically setting the ARPSYSTEMCOMPONENT property. As it's an MSI you should be able to run it through the Wise debugger and set up ProcMon to watch the HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\[ProductCode] tree (substituting your package's Product Code, obviously) with ProcMon, and/or watch the ARPSYSTEMCOMPONENT. Step through each action and wait for the uninstall key to be changed/removed. The offending action will be th eone previous to the currently-highlighted action.

Alternatively, set ARPSYSTEMCOMPONENT in your transform and then log th einstall. The log will show where the property was changed.

i got an exe which is extract msi in temp, msi(msi is created in Advanced Installer) will not show any entry in ARP during uninstallation one window will come saying that "action is valid only for products that are currently installed"
ARPSYSTEMCOMPONENT property is not there in msi
i tried creating mst and added ARPSYSTEMCOMPONENT=0 , but still it is not showing in ARP
some custom actions are there in msi like :
set property AI_ExractLzma to [AI_SETUPEXEPATH]
set property AI_ExractRLzma to [AI_SETUPEXEPATH]
6 more custom actions are there which are setting property that starts with AI_

Please help me out
thanks in advance.......

sounds like your initial install was done as PER USER and your trying to uninstall with another account.

No my initial install is per machine and i am uninstalling in the same account ...

but still this problem persists ..

varun,

Is the RegisterProduct action present and executed during install?
