We use WiX to create installation packages. I am new to WiX technology and am currently trying to seriously upgrade the installed application, but in a different directory than the previous one. For example, if product v2 was installed in Program Files (x86) \ Old_path \ Product, I would like to install the updated version of v3 in another folder C: \ Program Files (x86) \ New_path \ Product.
I changed the msi INSTALLDIR property to a new path. We tried to modify InstallExecuteSequence, added RemoveRegistryValues after InstallValidate to remove the saved old path in the registry, and did WriteRegistryValues to add new registry values.
<InstallExecuteSequence>
....
<Custom Action="HxPrepare" Before="InstallValidate">NOT Installed</Custom>
<RemoveRegistryValues After="InstallValidate" />
<WriteRegistryValues />
<Custom Action="HxFinalize" Before="StartServices">NOT Installed</Custom>
....
<InstallExecuteSequence />
But I do not see changes during the installation process, and new files are copied only to the old directory path. Can I find out where this old path came from even after changing the INSTALLDIR path? How can we make this change to the installation path during major updates.
