Thank you for your post.
Please accept our apologies for the confusion and frustration.
Firstly, are you using an evaluation copy of InstallShield 2021 R1? Or a fully licensed copy?
Secondly, if in the Releases View, you right-click Releases and select New Product Configuration, right-click the newly created product configuration and select New Release, select Compression > Uncompressed under the Build Tab of the release, then build the project, does the issue still occur? Hope that helps.
Please let us know if you have any questions or concerns. Thank you for your patience and cooperation.
