You don't say what existing version you are using?
The issue with the install folder isn't clear??
Do you mean you ftp'd a newer install version than the one that came with the existing version?
If you did then you should expect some incompatibility issues that don't even make sense maybe.
What are you trying to validate and why?
Sorry for the questions but your procedure is questionable and you give little detail of what you are actually doing for something I've never heard of 'validating' before.
Remove the install folder and does it all work fine.?
Copy current version as a backup and install properly, all files and see what happens?
Please indicate the version(s) you are using and want to install.
Looks like fun to be had.
