>Is(FILE_EXISTS, sTestPath ^ "Myfile.txt")

>FILE_EXISTS is an IS constant for the Is() function. Obviously, it will return false if the file does not exist. Depending on the result, you should be able to either use the ParsePath() function to extract the path and set your TARGETDIR for installation, or simply call the abort command.

Hi Jon,

I'm currently using the ISWI Pro. evaluation (my boss' hope is that using the interface I can learn the MSI table structure)

Will FILE_EXISTS act like DrLocator and check all local drives, since I don't know where the file will be located (if it exists)?

FILE_EXISTS isn't listed in the MSI reference, so I presume its part of IS scriping language, an MSI solution would be better with my requirements...

Is my solution that far off? < g >
