To whom it may concern

We are currently trying to utilize your software on windows. We have downloaded all necessary packages and followed instructions as to how to perform the model. Thus the installation has worked perfectly, however when trying to run the program an error message appears "Converting xls file to csv file... Error in system(cmd, intern = !verbose) : perl not found Error in file.exists(tfn) : invalid 'file' argument".

> The software works on Mac computers but not on windows. Could we please have some assistance as to how we can run these models on windows successfully.
