			== Information for InstallShield users ==

			HKLM Software\Microsoft\Windows\CurrentVersion\Uninstall\InstallShield_{GUID}

I migrated my software from an MSI installer to NSIS. Upon installing the new version of my software, I first needed to uninstall the previous MSI package. Here's how I did it:
== The Script ==
<highlight-nsis>
Function UninstallMSI
; $R0 should contain the GUID of the application
push $R1
ReadRegStr $R1 HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\$R0" "UninstallString"
StrCmp $R1 "" UninstallMSI_nomsi
MessageBox MB_YESNOCANCEL|MB_ICONQUESTION "A previous version of ${MUI_PRODUCT} was found. It is recommended that you uninstall it first.$\n$\n\Do you want to do that now?" IDNO UninstallMSI_nomsi IDYES UninstallMSI_yesmsi
Abort
UninstallMSI_yesmsi:
ExecWait '"msiexec.exe" /x $R0'
MessageBox MB_OK|MB_ICONINFORMATION "Click OK to continue upgrading your version of ${MUI_PRODUCT}"
UninstallMSI_nomsi:
pop $R1
FunctionEnd
</highlight-nsis>
From the main Section I then do the following:
<highlight-nsis>
push $R0
StrCpy $R0 "{48E5A72D-whatever-xxxx}"; the MSI's ProductID of my package
Call UninstallMSI
pop $R0
</highlight-nsis>
In my case I had to do this for every ProductID for each previous version of my application.
