Hi @wolfjg,

Thank you for your post.

Could you please clarify your request? Which specific function are you trying to use? In an InstallScript project or an InstallScript MSI project? Which project type are you using? Could you please elaborate in more detail about what you mean when you say you cannot find the InstallScript function? What is the expected behavior? What is the actual behavior?

Please let us know if you have any questions or concerns. Thanks!

Hi @wolfjg,

Thank you for your reply.

I believe you are referring to a major upgrade with an InstallScript project. A major upgrade automatically uninstalls the previous version then installs the newer version.

Please review the documentation at the following link for information on how to configure a major upgrade with an InstallScript project:

https://community.flexera.com/t5/InstallShield-Knowledge-Base/Performing-a-Major-Upgrade-with-Installscript/ta-p/4388

Please give the suggestions in this documentation a try. Do they work for you?

Please let us know if you have any questions or concerns. Thanks!
