Affects version: RayPack 2.1.5943.146 all languages.
When building an MSI file from a converted RPP project (a file which on the other hand was converted from MSI or RCP format), RayPack may show a warning claiming that source files are missing, although the files are actually present in the correct folder.
RayPack 2.1.5943.146 may incorrectly convert relative folder paths and produce incorrect results in RPSourcePath table. These entries are not valid paths.
Go to Advanced View in PackDesigner, and manually adjust all wrong paths from RPSourcePath table.
Install RayPack 2.1.5946.148 or newer to resolve the problem.
