Hi @chandni,

I’ve just checked with our Product Team and error 2503 suggests that there’s a problem with your Windows Installer and not with Slido. 

Unfortunately, there’s nothing we can do from our side. You’ll need to check this problem with your IT administrator or Microsoft Support to fix the issue. 


Please let us know if you were able to fix this or if you need any more help from us! 😊
