Thank You very much Rob for that hint! Only one question left. I have now experimented with two variants to solve the problem.
1. Setting the property Hidden to "no" Not bad because we have to make no other changes in the variable's definition. But unfortunately the variable value will not be encrypted anymore in the log file. <Variable Name="INSTALLFOLDER" bal:Overridable="yes" Type="string" Hidden="no" Value="[ProgramFilesFolder]"/> 2. Remove the properties Value and Type By my personal opinion that's up to no good, because we can define variables with different types like "string" and "numeric". That variant will be maybe problematic and could cause errors. <Variable Name="INSTALLFOLDER" bal:Overridable="yes" Hidden="no"/> What do You think, will be the best choice?
