InnoSetup takes wrong files

Question

Today i encountered an odd problem. In the Files Section i have two different .exe files, which are copied into the temp folder to do some stuff, and then disappear at installation time. All worked fine until the compiler took a version of my .exe and decided, that it won't take any other version of it. I recompiled it several times, deleted all Temp folder entries belonging to InnoSetup, restartet the PC, placed the new version of my .exe in another path and added it to the Setup, i even deleted all Versions of this .exe and built a new one, but nothing helped. InnoSetup refuses to take another Version of this .exe whatever i do.

Well then, here some Code:

MySqlDbCreation and XmlAndIniReplacer are two little C# Consoles.

Whatever i do, InnoSetup takes a version of XmlAndIniReplacer which i don't even have anymore instead of the one specified in the Files Section. Also it won't recognize the Flag dontcopy, which means, i can find the Console in the Application Folder. Whats wrong here?

It appears InnoSetup is finding information in a cache somewhere, noticing that the version hasn't changed, and is using that cached copy instead because it's already compressed and can save time.

Here's a way to fix it:

Build your setup. Use the Compiler Output window (View->Compiler Output) to see exactly what files are being included. You should check both the Parsing [Files] and Compressing: sections of that output. Note the exact path and filename it's using for the file(s) that are the issue.

Rename the problem file, both in the folder it's in and in the [Files] section in your installer script. Build the installation again, and check the compiler output to make sure it picked up the renamed file when it was parsing.

Change the script and file back to their original names. It should now start using the new version of the file as you originally wanted.
