InstallShield 2018 is having problems installing redistributables for VS 2017 x64 and x86 . Can reproduce this problem on several machines, including clean (only system updates) Windows VM's (7, 8, 10, 2012 R2, 2016, 2019).
So basically you're saying it's a Microsoft error? Its even happening for fresh Windows installations. Can't tell our customers to fix their registry because of this. That's a very unsatisfying situation.
