[wpkg-users] Question re upgrades

[Paul McGrath]

Hi Antony,
  See my Evernote example for remove

    <remove cmd='MsiExec.exe /X{0BE73D3C-B5AF-11E1-933A-984BE15F174E} /qn '>     <exit code='any' />     </remove>  <!--4.5.7.7146-->
	<remove cmd='MsiExec.exe /x{A53130A2-1EB8-11E2-BCE8-984BE15F174E} /qn' >     <exit code='any' />     </remove>  <!--4.5.9.7465-->   
	<remove cmd='MsiExec.exe /x{A23AADDA-3DBF-11E2-A6F2-984BE15F174E} /qn' >     <exit code='any' />     </remove>  <!--4.6.0.7670-->     
	<remove cmd='MsiExec.exe /x{9D8BAA74-5B7D-11E2-8273-984BE15F174E} /qn' >     <exit code='any' />     </remove>  <!--4.6.1.7860-->     
	<remove cmd='MsiExec.exe /x{DCA963D4-6AA2-11E2-80AA-984BE15F174E} /qn' >     <exit code='any' />     </remove>  <!--4.6.2.7927-->     
	<remove cmd='MsiExec.exe /x{4C8BBCC8-8363-11E2-A3F4-984BE15F174E} /qn' >     <exit code='any' />     </remove>  <!--4.6.3.8096-->     
	<remove cmd='MsiExec.exe /x{DDAFC46A-90E2-11E2-B700-984BE15F174E} /qn' >     <exit code='any' />     </remove>  <!--4.6.4.8136-->   

It error traps if it doesn't exist so that it doesn't fail.  You will have to do a lot of research if the uninstall code is different per version like it is for Evernote.  Other apps use a single code that never changes like Skype.

Paul:

Thanks. your answer is very helpful. One follow up question:

For packages like Skype that require a manual removal of the previous version (and we have the <upgrade include='remove' /> in the package.xml), it seems that the remove command that is executed is the one from the current version. Is there a way to include the remove of the previous version of the package?

Thanks,
Antony

If there is no patch but a new .exe or .msi then you will want <upgrade include='install' /> and you update the line for 'install' because you will want new installs to have the latest version as well as the existing installations (which will be upgraded).  You can also have <upgrade include='remove' /> because for some software previous versions must be removed e.g. skype.
