Yes you can:

If your main.exe sets its own default path when loading then its simply:

cMainExe = "main.exe Par1 Par2"  && Set up exe command with parameters list
RUN /N &cMainExe                 && Run exe without waiting

If your main.exe does not set its own path when loading then you can add the following path code:

cCurPath = SET("DEFAULT")        && Save current path setting
cMainExe = "main.exe Par1 Par2"  && Set up exe command with parameters

SET DEFAULT TO "X:\NEWFOLDER"    && Optional since main exe could set default path
RUN /N &cMainExe                 && Run exe without waiting
SET DEFAULT &cCurPath            && Restore to current path

IMO the main benefit from API_AppRun is: "...allows you to wait on termination or return immediately, and allows you to examine the execution status and termination code from an executable run by the class."
