[wix-users] MSI fails on InstallInitialize

[Steve Ogilvie]

Hi all,
So I have a MSI that all it does is run a custom action at LaunchConditions.
It is a prerequisite checker, that will run BEFORE our other MSI's to validate that all of the pre requisites for our installer are set properly before we actually copy any files.
I have a custom action that is called that checks all pre reqs and logs the results.
it doesn't install anything...
I have most pre req in our bootstrapper as well but most customers run our installs via GPO which doesn't support EXE's and hence they run our MSI's in sequence.
error log is:MSI (s) (A8:90) [13:55:28:709]: PROPERTY CHANGE: Adding REMOVE property. Its value is 'ALL'.Action ended 13:55:28: InstallValidate. Return value 1.MSI (s) (A8:90) [13:55:28:709]: Doing action: RemoveExistingProductsAction 13:55:28: RemoveExistingProducts.

Return value 3.

is this due to the fact I have a group component that is empty?
