That might work Blitzkrieg, but I'm not sure what you mean in the context of the FAQ install instructions, which are as follows. Where in this process are you proposing to move the files?
05. Begin installation of SH3 as normal
=> Change the target installation path so you do NOT install to the default path. Choose for example d:\SH3-stock
07. When you get to finish screen DO ***
NOT*** press "Finish".
=> THIS IS VERY CRUCIAL!! Do NOT hit it!
08. Execute the
patch-to-1.4b with settings "Run As Admin" and XP service pack 2.
For the version I use this file is for instance called "silent_hunter_3_dvd_1.4b_emea.exe"
=> It is crucial to do this with Admin privileges, do NOT try anything else or it is not going to work!
09. ONLY after #8 has completed, THEN hit finish.
