eyermonkey,
 
I don't know what MSXML4 is or where it came from. If you can't delete it, check the properties on it to see if is read only.
 
There are flags for installation properties. The default setting is do not overwrite unless a newer version. You can check Inno Setups documentation for more information on the flags.

I am trying to install MSXML4 with my project, but I am getting an error when I run the install file.
 
I think it is because MSXML4 is write protected because when I try to delete it I get an error saying I can't do that.
 
How do I resolve this?
 
PS - A question has been bugging me for a while: when inno installs DLLs does it automatically check the version and not overwrite if the computer already has a newer version?
