Last year we switched from Wise to InstallShield (the most buggy piece of software), then to SetupBuilder 5 (beta - Team5).
This week we have released an update with SetupBuilder 5.2 (build 1354) to 700 customers. Zero problems. Our team loves the product. Cool stuff!
You will not regret your purchase ;-) And the SetupBuilder community is always very nice.
