Error loading action list - The system cannot find the file specified

[andrewp]

I'm not unregistering anything else deliberately. The unregister step isn't always the step that causes the problem, and it's set to only include one file (e.g. PPTUL904.dll) non-recursive on a directory specified in a macro (def. different path to kinook). No deliberate registry delete is in the script.
The script is designed to build each vbp individually, getting files, checking out, running a script to alter the .vbp file re name of project (which, due to company requirements, is changed every build). Existing dll is unregistered, new dll is built over it using standard build step (no compatibility). The dll is then registered and used in the next step.
I can restore the registry hive using a reg file, but not being able to complete the build is very frustrating.
I'm checking through the script at the moment, but havent' found anything obvious yet.
So, do you think it might be a Visual Build Pro registration issue (i registered via the help file with 2 instances open by mistake). I can get it to build (before it refused re > 50 steps). Or am i clutching at straws

I don't know. Visual Build itself would not unregister the actions or delete that registry key on its own.
