Absolutely, but you need to make the directory part of the search path and not use absolute file references. IOW, make sure the folder containing your .VCX/VCT files are in the current path as set by SET PATH, and then omit the IN clause. The IN clause is only needed when you are referencing a class library embedded in another .APP or .EXE, so once having done your SET PATH

SET CLASSLIB TO (library name in a string, no path, no extension) ADDITIVE

would handle the whole thing.

>Summary: If the class libraries are separated into their own exe and acceses via SET CLASSLIB statement, can the application be installed to a directory different from where is was compiled?
