Without knowing how it has been set up -- I would still recommend extracting to a temp folder & manually installing ....


Some are set up fine -- if they are it should be self evident by the question asked during the extraction - such as 'location of FS2004 on your computer?' or 'FS2004 Aircraft folder location' ........


If the question is not specific or leaves you asking this question -- just install to a temp folder and install manually.

I have installed this RFP 742 many times and never had a problem.
