Hydro R choose version of R

I suggest improving the quotSet path to Rquot interface that is shown when the user installs HydroDesktop and runs HydroR for the first time.

In 95% of the cases, if the user installed R, he or she installed it in C:\Program Files\R\R-{X.Y.Z}\bin\i386\R.exe where {X.Y.Z} is the R version (for example R-3.0.1})

Here is how the quotSet path to Rquot could work when HydroR is run for first time:

Check if there is a folder C:\Program Files\R If yes, check for all subfolders that have the name like R-{X-Y-Z} bin\i386\R.exe inside them. If no, then R is probably not installed or it is in a non-standard location and user must set the path to R manually.
If more than 1 folder is found, Show a combobox quotselect R versionquot where user can choose the version of R.
After user selects the R version, check if the R.exe is valid and save the setting and start working with HydroR.
