Hello,
For now, you cannot condition a SSRS deployment report. I have added this improvement on our TODO list and it will be available in the next version of Advanced Installer. Thank you for your suggestion.
However, you can condition the "AI_SsrsDeploy" action from the "InstallExecuteSequence" table in the
Table Editor page.
Through its condition field you can condition the deployment of your reports. Unfortunately, you cannot condition the deployment of each deployment. Instead, you condition the deployment of all your deployments (if you have multiple deployments report).
If there is anything else I can help you with, please let me know.
Best regards,
Dan
