I obfuscate c# executive code using dotfuscator software, and then I created a setup file using installshield. the problem is installshield doesn't use obfuscated file for creating setup file . Work that installshield To build the setup file this is : Re-compile the code, And again makes a new executable code, The new executable code is not obfuscated, This file is used to build setup file.
I'm not totally sure I understand your question, but it sounds like you're saying you:
...and that worked. But then you:
Is that correct?
My guess is that in step #3, you have InstallShield pointing to the outputs from the basic build (step #1) and that you actually need to point it at the output from the Dotfuscator build (step #2). Dotfuscator typically puts its outputs into a Dotfuscated subdirectory, so you probably need to configure InstallShield to get its inputs from that directory, or configure Dotfuscator to overwrite the original outputs (from step #1).
Assuming you are using Dotfuscator Community Edition, you can configure Dotfuscator's build output location on the Properties page on the Build Settings tab.
Note that Dotfuscator Professional Edition has more options for how to do this integration, and full customer support. If you have Pro or are interested in it, please contact us for further help!
